Implement better pane management system about proton

[dvcrn]

Definitely possible but I couldn't find a plugin for this yet.
We could use the atom API to find all panes (and map the side bar to 0), check if the panel with index # exists and then focus it. Shouldn't be too difficult :)

Yeah I've searched for plug-ins many times and tried all of what's out there. Nothing is as good (for me) as spacemacs

If implementing this on our own isn't too hard, I'd love to see it.

[dvcrn]

Seems like this is what we want

Just realised that we are still missing SPC w m for closing all other panes (or 'maximising' the current one)

[dvcrn]

One thing that I still have in my head is, how should we treat panes and windows? Should we treat them as normal atom panes or just 'display options' for buffers?
E.g. in atom, closing a pane destroys all items with it. In emacs (spacemacs), closing a pane destroys the pane but leaves the buffers open.

If we want the same behaviour, we need to move all tabs / buffers to the active pane when closing others.

Besides that, are we missing anything here or can I close this?

I think closing buffers with a pane is fine.

It is likely that spacemacs keeps a buffer alive, because that is the emacs default. Here the atom default is to close them, so I don't see any harm in doing that.

I think we can close this, but we need to keep in mind the outstanding issues in #72 (a single [0-9] entry in keybinding list rather than 10, and labels on each pane so users know what number each pane is). I'll open issues for those items though.
