Is there a way to Undo actual changes only (as opposed to undoing every selection and playhead-movement)?
Iāve pondered similar questions to this, and as far as I am aware, no; there is currently no way to cull certain types of operations from the undo/last operation list. I find this same issue gets in the way of āRepeat Lastā being a valuable tool, since changing selection becomes the last used operation, itself.
Itās tricky, though. The undo system has been a point of contention in Blender for years, and for good reason. Itās a fairly complex topic, which requires much forethought and planning, both to setup a default, but also to allow flexibility for updates or customization. And as such, there are many different opinions on how it should work. Perhaps 2.8x will usher in changes which make the system superior to our current paradigm. Maybe thereās already a branch/addon which supports some of what youāre asking for, but Iāve never found them when Iāve looked.
Yes, I understand that, and I agree. I just hoped there were some hidden option somewhere.
That would absolutely awesome! I literally spend hours every day tapping āCtrl Zā (and then Ctrl/Shift Z when I go too far :)).
Itās doable for stills, but itās really time-consuming for animations because you need to run through the movie again and again to test out new edits.
And each time, you need to Ctrl-Z 20 or 30 times in order to go back just 2 or 3 edits. And you canāt just speed-tap Ctrl Z like 25 times in a row to get it over with because you never know exactly how many playhead-movements Blender includes in its historyā¦
CTRL+ALT+Z will show your undo history. You canāt select individual actions to undo, but you can go back an arbitrary number of actions in one click instead of doing CTRL+Z 10 or 20 times.
You can set Global Undo steps and memory limit in User Preferences.

Whoa, this is beautiful! Now, I can just skip those fifty 'Change Frameās in one go! Thank you very much, organic, thatās extremely helpful!
EDIT: I feel like an total idiot for not knowing this. 
This is changing my life, haha!
EDIT 2: This feature should be mentioned in every beginner tutorial IMHO. Itās changing my entire feeling for Blender. I mean, itās an awesome Undo-function and pretty much the same as PhotoShopās (which is great). Wow.
EDIT 3: To make this even better, it would be great if the Undo History could be open permanently, or as long as desired.
