Usability issues with forums

I just noticed the new forums feature being enabled in a server I'm in, and I'd like to express some concerns:

• Shift+Home/End does not select the text from the cursor up to the start/end of the text box in the search bar of a forum channel.
• Scrolling the post list just a little completely hides the Guidelines + Tags boxes in the right side.
• The "show more" button in the tags list when creating a new post is not being shown in wide enough screens.
• Only one tag being displayed usually does not suffice.
• The bottom bar of a post in the post list is too compact, reducing readability. It could be better to vertically align all different elements for all posts, adding appropriate spacing and moving the last activity to the right side of the bar.
• Archiving/Locking posts when there are no existing "older posts" will not display them  in the post list until the client reopens. After that, it seems that archiving posts properly displays them in the older posts category.
• In the sorting methods dropdown, the currently selected sorting method is marginally taller than the unselected one(s).
