Image properties Comment tab is a bomb and should be undoable
Operating System: All
Description of the feature
I keep a text project file for every Gimp project using Notepad++. Every entry is dated, and gives details about the layers, blend modes, parameters, special techniques involved in the creation of my final image etc. The file is stored in the project directory.
Image>Image Properties displays a dialogue window, one of the tabs is Comment. This is somewhat suited to keeping track of salient details instead, BUT one slip of the finger ("Use default comment") and you lose days, weeks or months of comments!
So perhaps the root problem is that the "Use default comment" button is actually a potential landmine.
