Jitsi Whiteboard Integration

Hi, I have two Jitsi tasks to do:

1) Include Whiteboard feature to existing Jitsi + Etherpad integration

I would like to run Jitsi with the implemented Etherpad inkl. the new Whiteboard feature. The user must see each other at any time having either the Etherpad or Whiteboard opened. On top of the basic view, Users can add a new Etherpad or Whiteboard layer by clicking on the “shared document” or “shared whiteboard” button. Ideally the button is integrated in the main menu-bar and always visible. Enclosed is a sample of how the integration could look like. Preferably I would suggest to use WBO (https://github.com/lovasoa/whitebophir). Here are some further information of how WBO was integrated to Jitsi: https://github.com/jitsi/jitsi-meet/issues/5295#issuecomment-646547042

2) Enhance the Screen Sharing and Video Quality of Jitsi

The screen sharing and video is blurry. Possible fixes that I found:
x) https://github.com/jitsi/jitsi-meet/issues/6409#issuecomment-738091208
x) https://community.jitsi.org/t/bad-video-quality-of-one-way-screen-sharing-in-latest-jvb-2-0/31748/11

Please describe briefly the integration steps and the time needed for task 1) and 2). Many thanks.

PS: As for the current integration I use Ubuntu 18.04.5 LTS + Jitsi + Etherpad.
