Great work 👍 Merged into the v5 branch with a few small tweaks. Thanks for contributing 😄

Thank you! My first pull reuest ...
When exchanging the gopher icon in my second commit I noticed a very strange behaviour. Somehow the writing direction seems to switch to right to left. At least this improved only after switching from a numeric only 1.16.5 to go1.16.5.
Maybe you have got en idea?

I'm currently planning to implement a prompt item showing the current battery level. Would that be interesting too?

I noticed that too, so I just used a different gopher icon 😂 No idea why that specific character is weird.

Sure! I think it might be difficult though with different operating systems and whatnot 😄

I am only able to test on Linux. I think I'll have to check for the linux specific /sys/class/power_supply. Maybe somebody else will be able to pick up from there ...
Are there more missing/needed prompt items?
I switched from ksh to bash to zsh to fish and used the current IP, battery level, free memory, CPU temperature, system load zsh prompt items.

If you're really interested in slaving away 😄 then Spacefish has a bunch of items that might be nice to port over. Specifically, kubectl has been requested for Tide in the past.

As for the ones you mentioned, I don't find them useful, and they're probably fairly annoying to implement due to the aforementioned OS issue, but if you want to, go ahead 😄
