The naming of triggers/conditions/actions is a great new recent addition and the fact that it creates a description for you is nice, but when you want to change it, the text it created is not editable in the rename dialog, so if you just want to add a small amount of text to make something clearer, you have to type the whole thing again. Once you edit it yourself it’s fine for subsequent edits.
Also, maybe a bug? if you have edited the description, then you go to rename and click on cancel, it will reinsert it’s own text again, which is not editable in the rename dialog.
