I am wondering, is there a question (on meta probably, and probably not even on Math SE) where someone would suggest making the 5 minutes post update limit longer? (the time before the next question/update is considered as a different one). I've just realized this is something I've been struggling for years, no matter how hard I try to read my posts before editing, I always find some improvement very shortly but usually close to that 5 minutes (15 minutes might be little more practical...)
Or even better, having the possibility to intentionally amend one's own consecutive updates to avoid it looking like an update spam
I have looked a bit through the posts tagged grace-period+feature-request, but I did not find anything. (I did not spend too much time with that, perhaps you might have better luck.)
