Delete multi tabs on slate editor?

[lou4uandme2]

Hi,

It seems that whenever I have 20 or more tabs in the slate editor with a dozen materials in each tab, Max slows down in performance, or sluggish.

If I delete all the tabs and keep the editor close, it works fine.

So is there a way to delete multiple tabs at once? Otherwise, I am deleting one tab at a time, which sucks when I have 40 tabs.

Thanks

Lou
