Issue Details

Description:

I installed a theme by following the command, and it worked.

fig theme aura-dark

But I couldn't see this theme in the selector of themes.

And I run fig restart again, but it didn't fix.

Hey @helbing! Thanks for reporting. We are in the process of migrating from our legacy Swift codebase to our new Rust codebase. Seems like the settings UI does not accurately reflect the available themes.

Should be fixed soon, but in the meantime you can just run fig theme <theme> instead.
