Canvas: selection of what show in cards at a great camera distance

[Tre]

Use case or problem

At a great distance cards shown as empty squares.

Proposed solution

Lets say, the right panel has a button with 4 modes:

1. At a great camera distance nothing is shown.
2. Text shown only if in start with #.
3. Text shown to first “.”;“!”;“?”.
4. Text shown as much as it fits.
   And, of course, obvious separate button and mode: mouse hover over card show enlarged read-mode window with all text.
