Yes, this has been helpful to save some typing, thank you!

Please also add this feature (same menu option or different one with "Copy message with fixup!" if difficult because it is a different window) to the "Log for" Graph window too.  It's where I almost always find the commit to fixup.

I miss this too.  WinMerge has this feature and is the easiest way to launch.

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?
