Aura Kobo Aura One newbie's questions.

[Yodo]

I'm just starting messing with my Aura One.I upgraded to 4.3.8966 and patched it ( didn't really customise patches). I installed KSM08 successfully with a proper patch for Aura One, then I installed koreader (version koreader-kobo-arm-linux-gnueabihf-v2015.11-894-gd168db9 - with a night mode, I think it is the latest one, first it didn't work but i found a solution in changing a bit of lua's code)) . My questions are:
1) Does koreader support on-the-fly light adjustment with two diodes (brightness and natural light) as in nickel mode?
2)How to enter KSM menu or koreader from nickel without shutting down the device?? The pngs in home screen dont work, they open as images.
3) KSM menu constantly remindes me of a wi-fi status and asking to turn it on or off.- How to disable that dialog?
4) Is there a way to see a history of words I looked up in a dictionary (both in nickel and koreader)?
Thank you so much!
