Great software. Especially the "lettermod" feature. It allows you to configure a key to switch to a layer / secondary actions if held for some time, but only if no other key was pressed within some time before. So secondary key actions don't happen while the user is actively typing a text. This makes it very easy to add homerow mods (adding Ctrl, Alt, etc to the homerow keys) without the struggle of accidently triggering them.
