comment How to inject an evaluated expression into a held expression?
@kguler but HoldFirst is not a "held expression" wrapper, it's an attribute.

comment MatrixPlot with Tooltips
After trying it, I think it's very fast, but I had a problem, when using the output of this graphic into a GraphicsGrid, it looses the custom coordinates tooltips. Anyway this is the fastest one!

comment Exporting held expressions through JSON
I think JSON only supports lists and rules and not arbitrary expressions.

comment Can the position of Tooltips be changed?
On Fedora it also appears bottom right of the mouse. Moving the mouse moves the tooltip.

comment Advanced Tupling
ParallelTableAppend shold be ParallelTable[Append, tried to edit but couldn't submit. I tried it and took on my machine 32 seconds (using AbsoluteTiming). Nice solution!

comment How to plot Venn diagrams with Mathematica?
Funny, maybe it should have a dynamic order of groups... and now I see that it has no labels...

comment MatrixPlot with Tooltips
I inserted a simple direction function instead of 1+xy and worked very nice! direction := 1 - 2 Boole[Thread[# > dim/2]] & and changed 1+xy -> direction[xy]+xy, {-1.2,-1.2} -> -1.2 direction[xy].

comment MatrixPlot with Tooltips
I thought also about doing my own matrix plot, anyway I wanted to know if MatrixPlot could be adapted to have tooltips. Here would be necessary to add the MatrixPlot behavior for non numeric cases (like Indeterminate). Thanks!
