you recommend within your post to download
P.A.'s GAPPS ('step 4') and install it ('step 11'); subsequently, under 'step 11' you comment that "...enabling [ART (Android Runtime)] made a very big difference for me in terms of smoothness".
However, within the article "
Meet ART, Part 1" that you provide a link to, the following advisory appears in bolded type:
"Warning: Do not try this with the Paranoid Android (or other AOSP) build right now. There is an incompatibility with the current gapps package that causes rapid crashing, making the interface unusable." (published: 11/6/2013)
You do not mention this conflict--between your recommendation to install P.A.'s GAPPS and the specific warning not to in the article you cite--within your post. This isn't a criticism--just an observation. You post helped me through the process of updating my NookHD+, compared with the particularly anemic (or plain incorrect) procedure described within the posts of others.
