ResizeIT 2 de Daniel Betz

Restore one of four preset window sizes (and optionally positions) using customizable keyboard shortcuts. Effortlessly adapt your workspace to what you’re currently doing.

Default keyboard shortcuts:
<ul>
<li>Alt+1/2/3/4 on Windows</li>
<li>ctrl+1/2/3/4 on macOS</li>
<li>Ctrl+1/2/3/4 on Linux</li>
</ul>

You can also select one of the presets to be applied on startup or to all new windows.
