Edit -> Preferences -> Commands

Commit Section -> Show Line Length Guides

Just something to give indication of recency/when, so for me, whichever is easiest.  Timestamp preferred.

Is this one in the plans anytime soon?

Toggle hamburger menu -> "Show only if changed" in the Commits or Journal view.

I keep wanting a 3rd perspective to have a 3rd set of view arrangements... each perspective arranged for working preferences.

This request is 3 years old and only my vote; has there been any thought about enabling custom/more perspectives?

Yes, "Move Commit to Branch..." would help my use case - I didn't commit to the wrong branch, but I want to have one or more commits that only exist on my working branch also on master/develop (to share them earlier than my branch will merge).  So my first two steps are the same as yours but my third step is a rebase on master/develop (or whatever is the target branch).

Well I see that 18.2 has this!  This one is complete.

Still regularly typing "fixup!".  Is there a reasonable feature to add to SG to enable clicking instead of typing?

Is there a solution to this problem yet - how to diff Word files within SG?

Well, of course just after posting I find the "Save As..." option on the context menu of a file in the Files view which handily prompts with the workspace location of the file.  That works perfectly with stashes!
