Virtual desktop selector

I am using the virtual desktop selector from mate.

It is nice that it shows windows dimensions and icons but:
- it does not allow arranging the position of a window inside a desktop
- there is no option to show window titles (very useful for terminals)
- it can't be a standalone window

So to make it large enough to easily see windows in it, it is necessary to either have a really high horizontal panel or a really wide vertical panel, but this is wasting a lot of screen space unnecessarily.

I used to have all these functions in fvwm, is anyone aware if there is any tool compatible with the mate desktop that can do this?
