Hi,
I just installed the PBP3.1 update and gave the MPLABX integration yet another go. Following Charles video and additional instructions posted here was easy enough to get it "installed" but that's pretty much where the enthusiasm died.

(I've only tried the simulator so far, in case that matters).

As previously pointed out, can't "watch" word variables. Everything defaults to "unsigned char" and I can't seem to change it.
Can't seem to set line breakpoints.
Can only set data breakpoints by knowing the absolute address (and only bytes, again).
No RAM gauge.
No syntax highlighting.
No code folding.

It's a TINY step forward me, but like Richard, I must say I'm really quite disappointed. Guess I'm stuck with MCSPX, it hasn't crashed on me since switching to Windows 10 but I haven't been doing much coding - and of course it does hardware debug even worse than MPLABX, ie not at all.

/Henrik.
