Print Master Gold
One of the reasons why I prefer nano the the behemoths that are Vi and EMACS is the discoverability of features. In many image editing programs, you have to guess where the function you want to use is and hope the developers thought the same way. Paintshop Pro (pre Corel) was the only one to get things right. (I.e. make the same guesses as me)
Example: Image Resize.
Is it a tool? a plugin? Will be next to the related (but different) canvas size or maybe crop? What is the distinction that decides if something is under the edit menu or elsewhere?
When you spend longer googling "How do I do x in y software" than actually doing it, there is a problem. Given that a lot of these functions are called the same, but are in different menus, a search/help system where you could type in the name would be amazingly useful. It shouldn't require an internet connection.
Sort of how the win10 start menu was intended, but failed miserably to do.
