I know that the pull out drawer doesn’t work if you load a URL directly (that’s a bug in Flarum itself) but it’s not working for me, despite coming from a Flarum page.
The tag one is odd… The tags extension has an option for minimum tags which should be checked server-side before being allowed to post. Even if they weren’t checked server-side, client-side protections should also be done (I’m not sure if they are, though).
I won’t be able to look into it, but I’m sure Alex and the devs would find a link to the thread handy – it could be as simple as the tag being hidden, or similar.
I’ve never noticed an item for the pull-out. I’ve always found that I’ve had to just put my mouse on the left of the page and hope it opens… where does it usually show up for you?
EDIT: Going to another thread let me open the drawer again. Not sure what’s going on with that.
