For all the new folks !
Glad y'all here. You might find the layout confusing at first. But it really is efficient, and information dense.
CoSo is best viewed on the web. Because you have more real-estate to set up columns the way you want.
If you search over on the left side, just above the text entry box for a Hashtag, like #cosomusic, or any other, a new column will appear. On the far right. You can pin this new column so it is permanent.
