12.0.0B1 and client bugs:

BootPlayer during JOINGAME leaves blank entries in the server's online user list
Alt-clicking doesn't work with Box on
Separate bookmarks for each tileset
The server-side script editor doesn't have the new features
OOO Scripts with many loops sometimes stop mid-script
You can get 0 of an item through scripts and modifying character data, but you can't drop it
Right-clicking in the map editor makes objects on the ground that can't normally be seen show up
Trying to edit the first blank ban in the list when there are no bans crashes the client

Requested features:

Interface font color
Find feature, bolded script names, and/or alphabetical ordering in scripting events list
Servers on different ports
Minimaps
Raised limit on Objects and Monsters
Raised limit on stats
A separate map editor with easy-to-use interface - possibly one that can edit multiple maps at once with a grid showing map edges
MissPlayer and MissMonster subroutines
