enricodx The migration was throwing an error so it should try to do it again. Did you try to just update the files and activate the extension again?
Other option is to get into the database and delete the extension from the installed extensions, it should run the table creation again next time you activate it.
You asked for a screenshot, here is one of the popup when you get a new achievement!
ctml I think this extension is very close to what you are looking for! I will definitely consider adding the options you mentioned but for now I will focus on fixing upcoming bugs. It has been quite a ride to make this extension since I pretty much had to learn everything about Flarum, Laravel, Mithril... and there is still so much I don't understand yet 😅
