I just upgraded from Ubuntu 19.04 to 19.10 (fresh installation). In 19.04, I installed an application from Ubuntu Software called dash to panel or dash to dock (it was one of these 2- which one? I don't remember).
It removed the top bar and merged the clock and battery etc. in my dock as:
After switching to 19.10, I tried installing this, because I prefer to have larger "work" area. I searched for both of these in Ubuntu Software, but apparently, I didn't get any search results for these. I'm not sure have it works in Ubuntu- are these extensions not up for 19.10 yet? If yes, are there any alternatives for it? If no, what am I doing wrong? I'm 99.99% sure that it is one of these 2!
