adding more groups is very easy - they don’t take much space and there is no performance impact, so we could easily have 32, 64 or even 128 groups. the only reason i had it at 8 was because the main purpose i had in mind for them was to make creating multi page interfaces easier, and i thought having 8 pages would be more than enough. i’ll be happy to be proven wrong though! the example with 16 radio button groups was a good one. curious how would you use 32 (or more) groups?
it’s the 1-8 numbers to the left of the grid area. disabled groups are dimmed, and the currently active group has a marker beside it.
