Tabs in TagSpaces

I would like to request the possibility of adding tabs.
This would make the moving of files (and folders, when it will be possible) more powerful.
Also (or) the possibility of splitting the window into two windows, as for example Dolphin can do.
This request goes along the line of making TagSpaces work just like a standard file manager enriched with tags (on linux there is no file manager that has a really simple to use and graphically intuitive system of tags like TagSpaces). But one can do this either improving the file manager features of TagSpaces or adding tags to the standard file manager (but considering the many different types of file managers available in linux, which in the end are not basically different from each other, it seems that adding tags to a file manager is a difficult work).
Thank you.
