[Q] i9300 CM11 M12 milestone --longpress back button option removed? topic

Hi all,

i9300 phone was due for a re-build. Was previously using CM11 m10, which had ability to set actions when long-pressing the menu,home,back buttons.

But AFAICS, m12 only offers longpress for menu,home.
The options for back button seem to be removed.

Is there an app I can get which will give me back the option?
(I used to use it to longpress kill tasks, which kept things snappy) and I miss it.

Regards.
