With our community growing we have reorganized several time the way topics are ordered. Each time we need to edit each category one by one to check the parameters are OK, change color, check permissions etc. And each time, we forget to unlock one or another thing, which is confusing for users.
It would be very convenient to be able to have all categories listed in a big table (or something similar) with all the parameters listed, and the ability to modify them.
I have the same problem, large number of private categories, and I assume you mean “with an UI”, but I fear the number of specific/corner cases would be quite large… what parameters should be in the table would be a bit cramped for all of them…
In the mean time you should be able to work something out with rake tasks :
