> This is much more difficult than I expected. How would you update something like - current machine's IP, Weather, BTC price, your inbox from mutt etc? These things do not require frequent updates, but also have no shortcuts to bind them to... I want to hack something for lemonbar, but can't figure out how to make different delay for different functions.

I personally cheat. I have a command cache_output[1] and I'll set the cache time to like 10 minutes for stuff like weather. That way, regardless of panel toggle status, I'm not doing "heavy" things.
