I saw a youtube video that they had moved the maintoolbar to the bottom of the workspace. To me this made a lot of sense. When I asked that person how they changed the location of the tool bar, they said that they had dragged it, like with the dockers, in an earlier version and just kept the same config after updating versions. When I tried to do this myself it did not work. So I assume that it needs to be changed in the code. But I have no clue what program I would use to do this. I have QtCreator suite installed. Is that what I would need, and if so, what are the files, and their location, that I should edit? I am not a coder so any pointers on what to change I would be most thankful. (I use Linux)
I'd really like to have it as a vertical position if possible.

Thank you.
