Every color change is added to undo history

[beasteers]

Currently, I need to hold undo for like 30 seconds to try and find the color that I had before and that's only if I can remember the hex code. It looks like atom has change grouping:

Call right before change: https://atom.io/docs/api/v1.31.2/TextBuffer#instance-createCheckpoint
Call on change I guess? Seeing as their is no changeEnd event: https://atom.io/docs/api/v1.31.2/TextBuffer#instance-groupChangesSinceCheckpoint.

If we need start and end events, maybe debouncing with a second delay could work?
