Folder portal and new text portal sugestion

Hello, thank you for this awesome piece of SW and I have some improvements sugestion.

Improve to the Folder portal. If I go through any folder I will be glad for step to upper folder with "backspace" key or back button on the mouse.

And here is one sugestion for new "text portal". This can open any txt file in "fence" like note app with autosave function when I wrote something into it.

It might can change color specific words from some kind of database?

Im sorry for my english it isn't my born language. Ty.
