Idea (Left) Side panel for progress and bookmarks

i like the side panel on the right for the notes.

Today im sitting in the meeting with my paper-WT and equipd Bible in front of me. I studied a day ago and so i was able to open the scriptures through the progress (last opened scrupitures) and thought it would absolutely great to have a optional side panel on the left to see theme or my lists of bookmarks permanently.

What do you think? Just a swipe and got the scriptures opened yeseterday or have all my bookmarks fe for a bible study to cklick on it one after another (inkl comments)...
