Here’s two minor suggestions for Aseprite.
Option to display the current frame’s tag name in the Preview window.
It can be in the window’s title bar (e.g. “Preview - tag_name”).
Option to “mark” two frames and jump between them with a shortcut key.
Frame 3 and 7 are similar. I want to make changes to frame 7, but I need to constantly switch to frame 3 to compare them. A shortcut key will make it faster to switch between them (i.e. instead of clicking on each frame with a mouse).
