I noticed two pretty significant issues with the current bandwidth limitation setting in the options for Vortex. First, is that the units are locked to Megabytes per second, and thus can't be changed to KB or even at least Megabits. Further, you can only use whole numbers in the field, and thus can't set .5 MB or .1 MB as a maximum.
My entire internet speed is less than 1/5 of the lowest amount I can put in this field. It seems that the very people who would need to use this option are those with slow internet connections, and setting limitations in units of whole MegaBYTES per second is useless.
