I've been playing around with possible approaches to customising the app's homepage.

I have implemented the homepage buttons using the reorderables package, however this has issues and crashes as soon as the items are long-pressed (an apparent known and fixed issue in that package that has re-occurred).

Alternatively, a package like https://github.com/knopp/flutter_reorderable_list might be more suitable, so I will give this a try.

Other thoughts are to have the arrangement done on it's own settings page to also allow users to show/hide buttons on the homepage as well as reordering them.

Was thinking of something similar myself. In that case there would be a settings page where you can change the order of the buttons and which buttons are present. I'll also add additional buttons, for example a trading post button. That button would simply navigate to the trading post tab, but would also show a preview of items and currency in the inbox like the wallet button currently does.
