I feel weird to create a topic for a such a detail, but I don't find any related topic.
I am a little stuck (on freeflarum, but I suppose it's the same on the admin panel of flarum) by the three option I have for message edit authorization for users (10 mn / until next answer / always).
"Always" is problematic for me (an user could delete all his messages one day, or troll by changing conversation several days afterwards), but 10mn seems really short (it's not even the time to re-read and check a long message you've written), and "until next answer" can be even shorter in case of a quick conversation.
While I understand the search for simplicity, this is one of the case for which Flarum seems to lack of options. Wouldn't it be possible, instead of "10mn", to just propose a field in which we could enter whatever duration we want?
