Hello! Professional concept artist of some 10 or so years who’s grown fed up with Procreate’s recent direction. big fan of the ipad app and have been using it for work for a year or so now.

Some PS things I would love to see, in order of guessed difficulty to implement:

• alt-click a layer to view only that layer
• layer colours! great for organisation
• PS’s D/X key functions: set black/white colours, and flip current colour to an alternative colour. Procreate has this too, but with current and previous selected colour, which is probably better than PS’s functionality.
• Pressing numbers to set brush/layer opacity is fantastic, and a great surprise to find in Artstudio thank you. What would be just as great is being able to press shift+numbers to also set flow in the same way, like in PS.
• The ctrl+alt+drag vertically for size is awesome, but I do miss it working vertically for opacity in PS, and horizontally for size.
• Ctrl+alt+drag only works on brush, not eraser, so when expecting the eraser to change size it switches me back to brush
  A select by color range would be incredibly useful
  

Non-PS things I would love:
Probably too hard but absolutely the one thing I would love is a smaller UI - I feel the text and buttons could even be half their current size, and using this with the apple pencil I’m sure there could be a lot less element padding. Layers especially have quite a bit of vertical padding which looks very nice, but means a lot of scrolling. I love being able to resize UI in Paintstorm, as I only need to have a big colour wheel and a large amount of layers visible - but when I come back to Artstudio it feels kind of like those TV remotes made for old people with the huge buttons 

Bugs:
the undo/redo buttons float above windows when I press the ctrl+z shortcut

Thank you for making files/shortcuts/etc not locked in like Procreate, features like ‘new file from clipboard’, for the smooth brush engine and all its PS-like features.
