Start Ediff by other frame

[Qiu-Kejian]

Hello. Thank you for this very nice package. Its so great.

I found it may be also convenient if there is an option allowing to start Ediff by other frame, in which case make it easier to switch back to ztree frame?

Sorry, I would like to cancel this issues. It's possible to switch back to ztree buffer by winner-mode.

Hi, I don't think the task is really for ztree, but would be really glad if you can explain your use-case in details. If you've found the workaround suitable please let me know and I'll probably add it to the wiki (it will be the first entry then :) )
