The only feature I'm currently missing from Overachiever is the reminder info in tooltips:

This is invaluable when going through areas for Loremaster or some such. I do realise that it would be a lot of work, so if you were to build the framework for this feature, I would be more than happy to help with converting the Overachiever data to your preferred format so we could get this feature implemented 🙂

Thank you for considering!

They are already working on it =)
They have a little preview thread of their discord to show the progress.

Gotcha, I'll follow on Discord, thank you 😄
