Inside the selectBLIDGui could we have the selectBLID_select button (the select button) have its accelerator set to "enter" so we can quickly select a key by pressing enter? Or could it remember the last key we picked so we don't have to pick one each time?
Also maybe the "Name" button on the main menu should be renamed to "BL_ID" or "Key" so it's clear what it does.
EDIT: Also I have to ask, could servers have the ability to change if players collide with each other or not? That would be super cool.
