Functional

Add the ability to expand the YAML panel to use most of the screen size and a way to reduce it to the original size.

UI/UX

Add an expand/reduce button next to the copy logs button. When clicked, the YAML panel should be resized to use most of the current view space. When clicked again, it should return to its original size.

Hi,

Very regularly we see that the MySQL container fails to start under the default 2mn timeout (120s). We've even increased that to 4mn and still fails (I've now increased it to 15mn to see what happens).

Anyway the point is that TC tries issue a SQL query to verify it's started during the defined timeout and if it doesn't succeed it just says that the DB is started, with:

00:11:17.
