Impossible to disable auto saves

[Tom Puce]

Hello.I'm using artstudio pro on Ipad and I would like to now if it's possible to disable completly the auto saving fonction ?
I already set the time period to 0 and uncheck the "auto save on document switch" but If I close a document or the app,it keeps all the modifications I made. If it's not,what is the point of have a "save" fonction ?
Thank you
(by the way it's a great app, and not a big deal or a deal breaker for me.but it would be realy great having the possibility to save or not and more confortable for experimentation than having to make some copies of the document)

Actually we don't want to completely disable auto-save. In iOS you should expect that system will close app anytime, for example when you are receiveing a call on iPhone (system sometime needs addtional RAM memory and it is killking some apps).
Besides we are doing the same as Apple apps like Pages, Number, Keynote and others.

Ok so I guess the "save" option is there in case the app crashes so I may not be able to auto save ?
If I may ask another question as I'm here.
I made a inking pen brush that I like with flow presure, but when I increase the brush size, it gradualy decrease my flow responsiveness(the more the brush is big, the more flow it as, no matter). What can I do to have my flow constant no matter what my brush size is ? (I hope my explanation is clear)
Thank you

Maybe try to decrease spacing value.
