The user interface of the clients seems a bit plain, and most actions are done through text commands and key bindings (sometimes confusing to new players).
Organize the spell list a bit. (its hard to find one spell in a large list)
Some sort of “quickbar” which items, spells, and skills can be assigned to slots
Server-Negotiated menu, that can hold commands added with plugins.
Should provide menu items for many more of the commands so text interface isn’t needed.
Add client side display of parties.
Add more virtual stats (bowmode, applymode, etc) so that client can be kept more up to date, as well as provide menus to change them.
Quit character menu item should probably be very clear that it means character will be destroyed and everything lost.
The quit character, disconnect, and quit from client may need to be clarified. Disconnect should probably be ‘disconnect from server’, quit character should perhaps be renamed ‘delete character’ or ‘kill character’ so as not to be confused with the normal ‘quit’ menu item.
