Just realized I've been sub'ed for over a year, but never left a review ...
Review: There's one - and only one - reason to not use this plugin, especially in VR:
If you're an incurable masochist who gets turned on spending aeons clicking through VaM's "GUI" & waiting for it to load after each click. Again. And again. And ... Maybe you also love crying bloody tears?
Everybody else: This is a GUI that actually deserves the name. It makes on-the-fly editing in VR an actually fun experience (as opposed to ... Rivers! of! Bloody! Tears!). There's so many ways it helps you organize & customize stuff - including itself - and access it rapidly & intuitively (Gaze selection! Automatically generated grids of preset!)
And go get the paid version already No, you will not ever regret it (though you might (!) passionately curse yourself for all those wasted hours that you "made do" without it).
P.S.: This review is mostly for the pre-2.0 version JJW published recently. I haven't even really begun to explore the possibilities of that new shiny ... (Friggin' multi-action buttons (!!!), ferfeck's sake!)
