For the help button, on the second level there’s a space between the duplicate and bag buttons that seems to be unused (if it is used for something, I haven’t seen it yet). You could move one of the multi-select buttons off level 1 onto level 2 and that would free up a space. I don’t know if you want to keep that open for a future feature, though. Maybe just swap a multi-select button from level 1 with the help button?
Changing aspect modes in Resize under General Settings doesn’t make a difference on my tablet. I have two options: Full Screen and Fit Screen, and they both do the same thing. It probably works on other devices, but not mine. Having aspect=true under [Render] fixes the aspect ratio, though.
