Great! Now the only things keeping me on Windows are Visual Studio (which can be tolerably replaced with JetBrains Rider) and... drums... the default mail client.

After using it for a while, switching to Outlook or Thunderbird is really hard, as their interface is extremely overloaded. The Windows Mail display mode with two panes, left being combined inbox with mail grouped by threads and large tiles, right for the content and quick actions, that ALSO switches to a single pane mode when window is narrow (E.G. when tiling) is just the best thing ever. Is there anything like that for Linux?
