App
Two smaller but useful things: the feature board, where you shape what gets built next, and themes, for changing the app's whole look.
Go to Profile → Feature Board. Suggest features and upvote the ones you want built next. Because the board is shared with everyone using the app, you need to be signed in, and you agree to a short set of community guidelines the first time. To post, tap Request a Feature, add a title and optional details, and tap Post Request. If anyone posts something out of line, you can report or block them.
Go to Profile → Appearance and tap a palette to try it on. There are four: Forest, Paper, Carbon, and Ink + Signal (the default dark look with an orange accent). The app reloads into whichever you pick. In the current beta build you may need to close and reopen Axis for a theme to fully apply.
