Booth - Add a search bar to the "Additional Logo section" - This is where the Booth background is added and though the platform remembers the images, you need to move through the pages 1 by 1 to get to the images. By adding a search bar this would shorten the amount of time spent looking for the correct image. Also, if you could add a logo without needing to save then publish (Like you can with Polls) that'd be great and shave off build time.

Thumbnail - Added in the Extra's tab - Thumbnail section - Platform currently doesn't remember the images added here and so you need to upload them for each session. It'd be great if it held a catalog (Like it does for presenters, logo's here) and also if you could search.

Sessions - If a VE has more than 15 sessions you cannot create it from a Master template. Instead you need to create the event with 15 sessions then manually add additional sessions by Add session. This allows you to add 1 by 1 the session type from the list (Or up to as many is available in the Master template itself. I.e if you have 5 live sessions you can select to add 5 live sessions at a time). You then need to wait for it to load before you can add again. It'd be great if you could select the type of session and the amount of these sessions you'd like to add in one go)
