I wish MassCategorization had a pause button like Mass Edit and Mass Rename because I often get ratelimit and badtoken issues and sometimes badtoken works the second time but I lose my place or just need to waitout the rate limit.
What I am trying to do is a mass like 4k pages remove multiple categories and I thought I'd try MassCategorization but I am almost considering just manually going to each page now due to the numerable ratelimit and badtoken issues.
Any suggestions about my issues or plans for adding a pause button?
Increase the delay - the default one literally shouldn't work with regular users, considering the default ratelimit is 40/min and it's one edit per second. It's made for bots, so you should set it to one every two seconds or something
Start from there and we'll see if you keep running into badtoken errors or something, that may be a problem elsewhere, perhaps it stems from the badtoken itself
