1. How do I eliminate or collapse the "My Communities" section?

Now that I've added Solidworks User Forum to my favorites I have no need to clutter my screen with the rest.

2. Please, please, please tell me you can make more than 4 posts appear on the screen at once?

I have a 32" 4K screen set at 100% scaling (meaning tiny text) and I still can only see 4 posts total. This is not the screen I usually have open to the forum. That screen is an HD screen. On that screen I can see 1.5 posts. That is completely unacceptable for actually being able to answer questions or anything else useful.
