Doesn't work well with Zen.

1. When creating new tab while tabs are split, it adds new to the split containers, visually in sidebar, but the new tab is separate.

2. Unlike Zen's default new tab, it creates a new tab right away rather than after confirming. Which is a bit annoying.

Any way to make this the default behavior? I mean, that the extension recognises the last used container, and open any new tab on that container.

On Mac, Alt+c works but only if focus is not on a text-entry area. Otherwise the normal Alt+c action types the letter 'ç'. Please change the key combination used on a Mac, or let the user alter it.

This add-on looks useful, but the shortcut is not working on mac.
Any idea?
