Description of Calendar entries to long

[idnovic]

Is your feature request related to a problem? Please describe.
The description of calendar entries takes to much screen space if the text is very long.

Describe the solution you'd like
The description of calendar entries should be cut at a certain length (like 10 lines) and only be displayed completely after a "extend" button was clicked.

Describe alternatives you've considered
A translate this text button would also help (see below) but it would wirk around the issue instead of to solve it.

Additional context
We translate the description from german to english and add it to the description field after the original language.
That means our descriptions get very long.
