Autoload, default status, input lags

[jaghili]

Dear Nicolas,

First, thanks a lot for this library !

I followed the readme file and added the small piece of code in my init but I am facing issues with it :

• I have to manually do M-x mu4e-thread-folding-mode to activate the folding mode, is there a way to automatically load this mode on start of mu4e ? did I miss something ?
• When loaded, I see everything unfolded by default (I see every emails), I'd like to see everything folded instead such that I can manually expand a pack of emails. I tried to change the variable mu4e-thread-folding-default-view from folded to unfolded, restart mu4e, but no changes.
• When manually folding emails, there is a severe input lag when I navigate over the lines with the up/down arrow. It seems to be when I pass over starred emails.

I pasted my configuration below.

Thanks a lot

I rewrote the folding code (see https://github.com/rougier/mu4e-thread) and it is now integrated with mu4e such that you don't even have to install it. The new version is much faster because it is done just in time (when you fold or unfold).
