IOS8 'skipping home button use' tweaks. multitaskinggestures, activator

hi, ive been an iphone 4 user for some time, my homme button became nearly unusable, so
i discovered multitaskinggestures and i found it one on the most useful tweaks out there.

i recently use an iphone6plus, and i would like to use home button as least as possible.
for preventing future problems, and because i found gestures faster than the home button.
i dont really know if this is the right place to ask about these matters.. if you know a more
suitable forums, please, tell me.

as you can imagine, left botton side slide in for control center, and right botton side to springboard.
the activator method doesnt work well or i didnt configure it properly.. and multitaskinggestures doesnt
seem to come any soon. so please any advice about it?
even more, with this larger 6plus screen is there any possibility of a left, center, and right side botton slide in?
control center,appswitch or springboard with just a gesture?

i know i may be exceeding the number of questions.. but one last more..
taking a picture with a 'gesture', from locked phone, lockscreen, springboard, of from any app???
i mean not openning the camera app as activator can do, just taking a picture without bringing the camera app

thanks for reading.
