comment Stopping variable from being updated by dynamic
then you still use Dynamic[F[x, y], TrackedSymbols :> {F}] and now only changes in F trigger an update

@WReach thanks for your 2 cents. I'll spend some more time with Query

comment Use Select to filter a dataset's sublists
Sticking with your origination approach this does the job for you: dataq[Select[MemberQ[#c, _?EvenQ] &]]

comment Module vs. DynamicModule in a custom plot function
@Choronaut how do you expect to get useful answers from misleading questions? State exactly what you need in your question. Until then just use DynamicModule

comment Why isn't SystemDialogInput opening the file browser, even using Method->Queued?
Or to put it another way the buttons within a DialogInput need to be preemptive but that is incompatible with SystemDialogInput, e.g. Button["Choose file", SystemDialogInput["FileOpen"], Method -> "Preemptive"]

comment Why isn't SystemDialogInput opening the file browser, even using Method->Queued?
I am surprised that you were able to do this in an earlier version. To me it seems counter intuitive that it could ever work. According to the docs: "The Wolfram Language kernel in which DialogInput is evaluated will block until the DialogReturn in the dialog is evaluated." Therefore if the kernel is blocked how could the SystemDialogInput function work when it needs the "Queued" evaluation mode due to the lengthy time required?

comment Type of Dynamic object and GUI-construction for file import
You need to go back to the drawing board unfortunately. Dynamic is not what you apparently think it is ...but what it is is explained in detailed in the docs and various tutorials.

comment New fonts in Mathematica 10.4
possibly just adding back support for fonts they had previously dropped. For example I notice "Webdings" in there. Supported previously then dropped now back.

comment How to interpret and extract the information from the JSON (JavaScript Object Notation)?
I'm voting to close this question as off-topic because the problem is that the JSON source is not valid

comment How to interpret and extract the information from the JSON (JavaScript Object Notation)?
the JSON is invalid. This is causing Mathematica to have a brain freeze. It also sent several online readers/converters I tried into a meltdown.

Use ImportString on the stuff you import and you should get a list of Mathematica rules or associations

comment Guidelines for planning custom GUI in Mathematica
@QuantumDot as a final observation I use MongoDB more and more these days and in an ideal world Mathematica seems like a perfect program to accompany it because associations can be very Mongo like but Mongo is currently mostly used in web development I think which excludes Mathematica. Also Tableau have already got in there and established a relationship with Mongo for their BI connector ...
