How to add new workspaces and systray

[Underscore30]

Hello, using this as my daily driver for a few weeks now and loving it. The only thing I really need is to make the number of workspaces higher (4 sometimes is not enough) and adding a way to see the systray(I tried other systray programs like stalonetray but they don't work so well).

Could you please point me in the right direction on how I could add these things?
