request: ability to configure settings from within the client

[williamkray]

i'm just playing with iamb for the first time today (fun!), but it's a little obnoxious to mess with the app, realize i want to change a setting, edit the config in another terminal, quit iamb, start it again, wait for it to sync, get hit with this bug and have to check another client to make sure i'm not missing anything important before running :unreads clear, and then do it all over again about three minutes later.

most tui apps like iamb offer the ability to set the configuration dynamically, perhaps with a :set settings.image_preview.protocol.type=kitty command structure, e.g.

if this were vim, that setting would of course only work for the current session... but if it were a more intelligent tui app, it could also store this configuration automatically into the already-loaded config.toml, to be reloaded next time the app was opened.

again, if it were vim, at the very least there would be a command to reload the config file. this is less ideal, but may be simpler to implement.
