That looks a very useful tool, thanks. I think it could be just the thing for bulk renaming photos to standard names.

Thank you for this. I think this has some of the operations I need, I will dig into the code.

So git-annex should let you just pull down the files you want to work on, make your changes, then push them back upstream. No need to continuously sync entire collection. Requires some git knowledge and wading through git-annex docs but the walkthrough is a good place for an overview: https://git-annex.branchable.com/walkthrough/

I seem to get pop-up notifications for free in GNOME/Fedora by setting these levels in /etc/UPower/UPower.conf:

UsePercentageForPolicy=true
PercentageLow=50
PercentageCritical=20
PercentageAction=10

I think you can also configure the system to take action when it reaches the lowest level with e.g.

# The action to take when "TimeAction" or "PercentageAction" above has been
# reached for the batteries (UPS or laptop batteries) supplying the computer
CriticalPowerAction=PowerOff

However I don’t know how to get these GNOME “Power” notifications to play an audible sound (without turning on notification sounds for ALL notifications). The best I could find is this: David Bazile / gaudible · GitLab

There’s talk of better control of sound notifications in GNOME 47+, but looks like nothing much has landed yet: Notifications in 46 and beyond – GNOME Shell & Mutter
