Add the ability to automatically save the width and height of blocks in the log viewer.

When I check logs, I always have to:

• enlarge the block with the screenshot to immediately see which elements are in action
• expand the test case tree on the left to see which test case we are checking at the moment.

I suppose that other users also suffer from such inconveniences, and maybe they have other wishes to view the logs.

That's why I think it should be possible to adjust the display once and keep it. So that you don't have to change the display of the log window every time you run test cases.
