Suggestion: Add "Auto" to size option

[danilagalimov]

Currently there are 3 types of Window preview sizes: Small, Medium and Large.

However, I'd like to utilize as much screen space as possible,so I suggest to add "Auto" setting which will select the maximum available option based on Windows which are available for switching just when you press switch start key, so, if all windows can fit on Large screen, it is selected, if not - then Medium and Large accordingly.

Hey, this is a very good idea. We also thought about such a feature when we refactored version 7.0. Due to the large changes in the refactoring, this feature has been temporarily shelved. Similar features can be added later, and PRs are also welcome.
