I think all sessions windows panes is OK, at the moment only input is filtered by the control client's session (because it is high volume).
pane-mode-changed it would be nice if it showed the mode but TBH it is probably not worth the trouble if doing ls/lsp/whatever is fine (can add a format to show the name of the mode if needed). For client-session-changed I suggest splitting it into %%session-changed (for this client's session like now) and %%client-session-changed (for another client's session). You'll need to loop over all clients and choose which one to use, like it does for window-renamed etc. On Tue, May 02, 2017 at 08:37:16PM -0500, Joshua Brot wrote: > Thanks for the pointers.
