LAYOUT TABS - Suggestion/wish

Not sure if this has been brought up.

On my larger objects I can have a lot of layout tabs going.
Sometimes I get to a point where i have to divide the pages up to multiple files because Rhino lags too much. Should it not be lagging?
Im wondering if there is a way to quickly delete multiple layout tabs? So i do not have to individually go in and delete each tab … I end up having to do this for multiple files as I try to separate the files…

couple options.

I use Fabtools - LayoutManager, which is severely outdated but still works.

This is a recent plugin.
