I'm not sure if this is intentional or not, but right now you can only select text in an input control using the mouse, even with the directional macros removed. In most text boxes, you can select text by holding the shift key and then pressing one of the arrow keys. Would this be possible to add for BYOND skins?
Also, input controls are annoying in how they handle double quotes. Right now, the best option (other than maybe using client/Command or browser interfaces) for input controls that execute one specific verb is to set the input's command property to something like say . The problem with this is that if the player hits the space bar right away, then a double quote appears at the start of the text box instead of a space. If the first character typed is a double quote, then if another double quote ever appears, then spaces typed by the user are filtered out by BYOND and when they hit enter, the say verb won't be called but instead be replaced by a 'Sorry, the following is not valid' error. Setting the control's command parameter to say " will fix the first problem, but cause any double quotes with at all with text after them to trigger an error. Finally, using the no-command property might fix this entirely, but then the user can't hit enter to submit the text (if a macro has been set for the enter key, it isn't run when an input control has focus).
One more request: could Click() and DblClick() be called for a couple controls other than maps, grids, and statpanels? Specifically, it would be nice to be able to close a tab when the user middle clicks it.
