I often work with multiple plugins on each layer. When I manually solo a layer in a project, I notice a massive increase in performance.
I couldn't find a solo layer module that automates this action.
So I thought it would be handy to have a module that kills the visibility of all layers across all layersets, except of the focus layer. It would be even more handy to have a "kill visibility of all layers in Group A/B" option. So when you have multiple layers active and visible in group A, you can kill the visibility of all layers in group B (on all layersets or only in the selected set).
To bad I can't program this.. anyone interested?
