I’m in the same boat as you and never found anything for Samsung tizen os. Smarttube is android based only and anything streamed to a Chromecast still has ads.

Edit: okay I thought let’s search one’s more. And there is tizentube did not try it yet but seems promising

Edit a file, writing a quick shell script or whatever in the terminal. Nano is great. I don’t see any use in learning vim or emacs. If I need something more I’m going use a gui editor anyway.

Don’t get triggered anyone it’s just my preference
