Hello,
I have an idea for flagging.
Suppose your reading a post and you come across five different reply to that post that are say spam or off topic. well it would be annoyin to just press the 
over and over again for each post so my suggestion is.
What if we can select multiple posts then press one and one reason and it flags those selected ones all at once then a staff member can do a group review and handle all the flags at once say there all spam well all can be deleted at once or they can remove a selected post from that flag group making it it’s own flag and they can just handle the grouped ones at once then the ungrouped one it’s self.
Let me kknow how this might go
