Since we now have both jTab and ABCjs on active on the meta, it's time we had a specific place to test both. Use the answer space below to test and stretch the limits of both jTab and ABCjs for both on-site documentation of how each work and to find where there may be issues encountered.
Note: The formatting does not seem to kick in immediately when you save the changes. You need to re-load the page for the formatting to apply to the post.
Basic chord progression in jTab:
Cmaj7 Dm7 G7 Cmaj7 Not the most obvious changes on the fingers. Let's try try the barre forms:
%X/X.3/1.5/3.4/2.5/4.3/1[Cmaj7] %X/X.5/1.7/3.5/1.6/2.5/1[Dm7] %3/1.5/5.3/1.4/2.3/1.3/1[G7] %X/X.3/1.5/3.4/2.5/4.3/1[Cmaj7] Not rendering quite right. Let's try one per line in a code block:
%X/X.3/1.5/3.4/2.5/4.3/1[Cmaj7] %X/X.5/1.7/3.5/1.6/2.5/1[Dm7] %3/1.5/5.3/1.4/2.3/1.3/1[G7] %X/X.3/1.5/3.4/2.5/4.3/1[Cmaj7] Not rendering quite right. Let's try one per code block:

%X/X.5/1.7/3.5/1.6/2.5/1[Dm7] -
%3/1.5/3.3/1.4/2.3/1.3/1[G7] -
%X/X.3/1.5/3.4/2.5/4.3/1[Cmaj7] That's pretty ugly. Let's get it fixed.

It looks like the \slurDashed command is trigging jTab or ABCjs (or something else).
\slurDashed, but I'm not sure why this is causing issues; I can't find anything like it in the jTab or ABCjs documentation.

I was going to ask about beaming, but if you put a space between the two groups of four Gs then it gets beamed as two groups of four quavers.
