When I looked, it had the same problem that Dropbox has with this: a textual listing with only timestamps. I need semantic info! Show me the differences. Don't make me choose from this arbitrary list. I want to scan through the versions very, very quickly.
Not sure what you're looking at, but IntelliJ 2020.3 gives me a list w/ timestamps in 1/3 of the modal, then a diff viewer in the other 2/3. I can down-arrow through the versions and the diff updates.
I use view local history of selected so I can blame myself and view git history of selected to I secretly seethe at some one who left the company 3 years ago.
Yep, it's quite a handy feature at times. I don't use it a ton, but it is very helpful when I want it. One very nice aspect is that you can scope it to a specific section within a file (the same can be done with git history as well).
Personally, when I'm ready to submit a pull request, I usually do a soft reset to the point where I branched off from, then redo my commits and force push to the branch, for exactly that reason. I can't remember exactly which lines I've changed over the past few days unless I see all the diffs together.
