1) The sidebar behaves the exact opposite of what the documentation suggests. It vanishes when the tablet is rotated to landscape mode, and appears when rotated to portrait mode.
2) You cannot access the advanced actions menu for a token on the map by tapping and holding a finger on the token. It only brings up the basic actions (adding stats and colored markers). Thus, you can't add the token to the turn order, move it to another layer, etc.
3) When attempting to single finger tap and hold on the map to cause a ping, the ping is happening in the upper left hand corner of the screen, not where my finger is.
Usability concerns:
I can't even get pinging to trigger at all when zoomed out to 50% or less, despite my best efforts to keep my finger completely still while tapping and holding on the map.
I would assume the same is going to go for accessing the advanced menu for a token (to be able to add to turn order, etc), when that is functioning. More leeway needs to be built in for these actions when the user is zoomed out to 60% or less, etc.
I didn't read anywhere an option to ping (like the players can also do) versus ping and recenter the map for everyone (only available to GM).
Pinch in and pinch out to zoom in and out of the map would be fantastic.
Bigger icons for the toolbar, especially when in portait mode, would be fantastic.
