New screenshot & 2 new features
Quick test only
Upgrade CodeMirror to 3.02
Matchhilight & autoCloseTags updates

CSS class changed needed for matchhilight and removed color setting
snippetFrame now unused, removed
2 new options set to autoCloseTags and highlightSelectionMatches
No longer setting thisCM.matchHighlight anymore
Set a if 1==2 condition on the previous (and quite ropey) code that did
autoclosing to stop it happening, will remove next.
Remove old close tag system, tweak highlights

Old and quite ropey close tag system removed in favour of the
CodeMirrror closetag addon
2 x classes to define highlighted text now forced to be white on blue
everywhere
Selected text forced to be white on blue
tagNestExceptions array removed

No longer used (was only used by the ropey close tag system, now
removed)
Allow opening of empty files

Allow 'empty' to appear in the MIME type, so we can accept things such
as application/x-empty, which indicates an empty file. Wouldn't open
them previously.
Change of operator to consider empty files

Was giving false positives on false, !==false is what we require here
Considering empty folder should be opposite arg

Should be if the childNodes.length < 3, was doing the opposite. Oops!
Inform user if there is no file/folder to copy
Fix bad comment tag, revise matchhilight styles

The comment after .CodeMirror-scroll should be inside /* */
Merge matchhighlight and the focused version, add pseudo styles to
override main selected style. May look at changing this in future.
As we removed a class, the tab class is no longer the 6th, but now 5th
class
Adjust style values

Now we have an extra stylesheet, this should be [3] not [2]
The class ref for the tabs class is actually [5] not [4]
Hide paste option until we have copied something

Changes display from none to block when we copy a file/folder ref.
