So I have 2 suggestions, 1 of which I think has been suggested but oh well.
I think the "edit" button should be removed from your posts after the thread you posted in has been closed (for some reason it still shows up because 30 min hasn't passed yet), but it's not like you can edit your posts after the thread is closed so I think it being there is just useless...
Ex:

My second one is to be able to quote someone (or to get the quote code) even after the thread has been closed (of course you won't be able to post it). Kind of like when you click the post# beside a user name in a thread, it brings up a small box with the URL to that post and then you can copy/paste it where ever. I think it's a hassle to have to type it all out again, even though you could highlight and copy/paste the text, you'd still have to know how to put in the date/time, etc and not a lot of people know how to do that or they're just lazy. Either way I think this would be a good and harmless addition.
Lmk what you think
