Glad to see this being updated in an official capacity again!

Not sure how much effort you want to put in to continued development, but the new warbound banking system is account-wide and holds gold/currencies that this addon would do well to track.

I have (very roughly and quickly) put together a version for warbanks (gold only) if you're interested in looking over some sloppy stuff clicketz@7e9d1f0

Mostly though, check out https://warcraft.wiki.gg/wiki/Category:API_namespaces/C_Bank with Enum.BankType.Account being used for warbanks

Warbank also makes realms essentially pointless to track too since everything is effectively account-wide now.

"Not sure how much effort you want to put in to continued development" - Essentially very little, hence why I brought it to github to open it up so more people can get involved if they like, and try to keep the addon functional as best as I can (always annoying when an addon you've used for years dies and the sole dev disappears).

When I get a chance I'll try to pull your code in and take a look, judging by the screenshot it looks very nice.
