maybe these have been suggested and I used the wrong search terms, but I did look.. honest

die colors, roll comments, and roll batching
* DIE COLORS
Something like a 'C' parameter, that indicates the die should pick a random color as well as a number, from say.. black, red, green or blue
/roll 1 13 C
"player rolled blue 7"
or, optionally, the player defines color, it must match one of the randomized one..
/roll 1 13 C red
"player rolled red 11"
* ROLL COMMENTS
The idea is to be able to add a comment, thats appended to the roll, much like emoting while speaking..
* dewed yawns "well its late I'm off to get some sleep"
/roll 1 13 C "HOUSE ROLL"
"player rolled red 11 HOUSE ROLL"
* ROLL BATCHING
This just allows you to do multiple rolls with one command, use the asterisk *, and a number from 2, to say 7 or so. Batch numbers outside the range are ignored
So for instance,
/roll 1 13 C *3 repeats the roll command 3 times, echoing a single line of the "rolled" values
"player rolled green 7, red 3, black 3"
I think these options would greaty expand the type of games one could play using the dice system, certainly poker comes to mind, roulette etc.
