I see and feel it too with the brushes I use, something's definitely not right.
And it's not different sensitivities between the two, I made sure to make it the same

I think the current autosave implementation is pretty outdated.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.
