Hi, thanks for the detailed review! Regarding your question about stashing directly to a particular stash, if you have the sidebar open, the blue buttons with downward-pointing arrows (the first two buttons under each stash name) will do this, but there’s no way to do it from the context menu currently.

There’s an open feature request here that you can keep an eye on though: https://github.com/josh-berry/tab-stash/issues/30

Thanks again and I’m glad to hear you’re finding Tab Stash useful!
