 - [x] unmute the player on each module change?

+- [ ] add a 'muted' indicator outside the iframe

+  that module (forwards is fine)
+- [ ] resolve the 'flashing'/re-rendering of the progress bars
+   - [ ] hide the progress bar until maybe "unmute"?
+- [x] remove controls, since we want to be nonlinear
+- [ ] don't let the YouTube iframe take control of keyboard events
+  - [ ] make it unclickable if possible
 - [ ] possible to "hide" iframes that have already been loaded and "show" them on selection?
   - [ ] if so, can you load all the iframes in the background on first page load?
 - [ ] remove unused code now that we're totally modular

 - [ ] (depends on above) enable search
 - [ ] add checkboxes for 'want to watch'
 - [ ] gray out watched modules
-- [ ] resolve the 'flashing'/re-rendering of the progress bars
 - [ ] related to above: don't re-render the progress bar to "done" or "empty" in current module
   right before switch
 - [ ] make it work decently for mobile!
