All reviewer action should have a snackbar

[Arthur-Milchior]

With exception for things that are clearly shown such as "add note", "edit note", "show card information",

At the very least in full screen, there is no indication that the gesture/shortcut was correctly applied. In non full screen, that still seems good practice.

The missing notification are:

• enable/disable whiteboard
• flag card
• mark/unmark note
• answer card

I must note in the last case, when full screen is disabled, the answer button seems to appear tapped quickly, that confirmed which answer was selected. This is not available in full screen

Those are self evident actions. Flags and Mark have symbols that are displayed to the user even with Fullscreen enabled, and the whiteboard changes the whole toolbar and UI interaction. A "notification", which I assume you mean a snackbar message instead of an Android standard noitification, is mostly redudant.

In full screen, the flag is not displayed. Nor is the "marked" status.
Admittedly, showing those icons would answer my request. However, as I want fullscreen, I would not actually want for the flag to take room on the screen during review.

Regarding "answer", it's evident that an answer was registered. Not always that I entered the answer I expected to answer. I use the four swipe gesture for the four answers, and sometime i'm so much in diagonal that I wonder whether I used the right one. When I'm not in full screen, I don't really have a problem, I feel like I see the change in color on the answer button and I feel confident.
Now that I'm trying fullscreen on my new tablet for a different kind of review, that slightly stresse me out

Regarding whiteboard, it's only self evident once you try to use it, which don't seems to be good accessibility practice.

I was thinking about the Hide system bars option, not the Hide system bars and answer buttons option which hides the "mini bar" despite the value of the Show top bar setting. Uncoupling them would solve your mark, flag and answer issues.

The Toggle whiteboard snackbar is acceptable.
