Sure but when adding image exporting "name " options, please also keep the option the way it is right now, that it automatically numbers the images in the apple gallery (Just to avoid that every exported image would be named "untiteld" if you dont add a specific name)
I'm not sure I understand, I don't think apple allows rewriting files, if the filename is "name", they always go "name(1)", "name(2)" and so on, that's why I suggest adding the option to change the name while exporting, so I can tweak that instead of having the default naming from apple, or if I export the drawing at 50% size change my filename to "name - half" or stuff like that. Hope it makes more sense now ^^U
And yah, the renaming option would have the current filename already typed in, like most apps/programs do, so people who don't want to change the name don't have to do anything else

Some apps like Mega allows picking the name up before I save the canvas to that app, so I don't really have that problem, but it would be nice to have it for the apps that doesn't allow it
