I think the current autosave implementation is pretty outdated. Artstudio only autosaves after every certain period of time, minimum of one minute.
1. If working on a large file, autosave can take an annoyingly long time to finish. It pauses everything and you have to wait until it's done.

2. Artstudio delays autosave if you're painting, only saving when you aren't doing anything. This sort of makes sense because if it interrupted you every single minute it would be incredibly obtrusive. However this can be annoying because say I work 10 minutes nonstop and the app crashes, throughout those 10 minutes it doesn't autosave a single time, so I'm back 10 minutes.

So my question is why doesn't artstudio autosave seamlessly after every step? I hope it has the capability of implementing this as it would solve every single problem, and I think this is what every software out there does except Artstudio.

Keeping it the same as elastify is not really an argument for this change, since you spend less than a percent of actual drawing time in elastify, so it's okay for the UI to take up space during that time. In the other 99.~% while I'm drawing I'd prefer it to take up as least space as possible. Honestly I've never struggled with the sliders so I guess your point of view seems foreign to me.

As for nudge mode, maybe? I've never had that much of a problem with the issue this would solve, I use three finger swipe to adjust brush size and it's pretty easy to nudge brush size by very slightly moving your fingers. Maybe this could solve both your problems?

We will not do it in a near future. Remember Artstudio is mainly drawing/painting app, not an animation app.

Ah, thank you for your consideration, that's unfortunate but I understand. I just hope that this is not the sole reasoning keeping it from being implemented, because there are a few heavily drawing and painting focused software that branched out into animation which have this feature.

I agree, this feature is what separates toy animation software from more authentic ones.
I do not envy the person who has to implement it though... I really hope it could be compatible!

The biggest two features will be:
- animations
- vector pen tool

Animating on artstudio sounds like a dream... depending on how thorough you want to be with it, there's an app I could recommend you look at called callipeg which is focused entirely on animation. Though I know adding an elaborate animation interface is probably unrealistic, so even a simple frame by frame animation option is something I'd really be looking forward to!

it's there for me...

Don't worry, there's no controversy here, I stated multiple times that I'm not arguing for the removal of this feature, I just don't think it should be the default.

My point wasn't at all "I don't use the line tool to crosshatch, so this shouldn't be implemented". It's that I don't think crosshatching
*with the line tool* is a significant enough technique to change the default way the line tool works, since that seemed to me the reason for this change. This was especially because I've never heard of people using it to cross hatch; freehanding is the only method I've ever seen- in digital work as well. If you say many other artists use the line tool, then I'll take your word for it.

Again, I like the feature, I also think it's an improvement and I'm glad we got live preview as well. I just think it should be toggleable since having to change brush dynamics just to use it the old way (and the way every other program does it) would be a pain. Photoshop does have a very accessible toggle like this for brush tool sensitivity, and that would be a good solution. 

About the main topic of the thread, honestly I would like to make a case against this change, or at least have there be an option to turn it off. I think this change is very interesting and experimentative, which is definitely something I love the app doing.

However, I don't think having this as the default is a very good idea. The only reason I've read so far for this change would be for hatching, and I do think it improves the line tool's practicality for it, but is it enough to justify fundamentally changing the line mode as a whole? I'm not so sure.

Mattnava provided examples of traditional work using crosshatching, but I don't really understand what any of those drawings have to do with the line tool. In my opinion those examples would be a good case against this change, as they are done with a pen/pencil, which is the equivalent of freehand. To be frank, I don't think anyone should use the line tool for cross hatching. I don't crosshatch or use it in my work very much, but to me using only straight lines leads to a very rigid effect when using it to shade rounded form, as cross contour lines are rarely ever straight. ​I could see it being used for a stylized effect, or rendering flat objects, but I don't think this justifies changing the line tool fundamentally.  I think you would have a great deal of trouble finding an example of a drawing crosshatched using the line tool. 

So why not change it? Let me reiterate really quick that I'm not advocating for the removal this change, but rather having it as an option, and not the default. I don't think there's anything too fundamentally wrong with this addition, I think it's great as my philosophy is the more features the merrier.

The first reason is that to my knowledge every other software doesn't have this function, and use hard lines as the default. I know this isn't the best reason, but I think a feeling of familiarity when using a new app is essential.
The second reason is that if this is the only option, it removes the ability of creating those consistent hard lines without changing brush settings which is very inconvenient.

I hope it is understood that I don't mean anything personal, and don't really have any stake in this but I just figured I would give my two cents about this change. Thank you!
