[Q] TW features to keep and remove, xposed?

N910F. After playing around with a TW ROM, I've decided I need Xposed. I miss the customisation that was possible.

There are also a few features I don't like about TW:

* the S finder notification bar
* the quick settings bar
* large fonts in several areas (despite setting font size to tiny)
* bright colours etc.

... but I would like to keep the multi window facility from TW.

* Would it be possible to remove these features from a TW ROM using Xposed? Or add multi window to an AOSP ROM?
* Do I need a deodexed TW ROM for Xposed? Anyone got this working or is it still buggy?
