[DQSD-Devel] Tool tips on Help Menu

[Will D. <dq...@in...>]

Dear All,

I have checked in code with support for tooltips on the helpmenu.

They're currently disabled by default - there's a new parameter in 
preferences.js.

I've also done a heap of work on helpbox.js to make it load 
faster.   Interestingly enough, there's over 100k of HTML generated to make 
that table in the middle (Glenn probably knew that...), so the way in which 
string catting is done is important.

I suspect it would render still faster if the HTML was delivered to the 
window in more chunks, but I haven't bothered to play with this.

Cheers,

Will
