Hi Prasenjit,

thanks for your thorough testing! All should be fixed, now, unless stated 
otherwise, below.

Had noticed and corrected this a few hours prior to your mail.

This option did not exist, when Stefan wrote those plugins. I've changed it, 
now.

I guess we need an option "min_inclusive" or something like that, to allow 
values greater than, but not including 0, so we don't need to arbitrarily 
limit to 0.01 (while e.g. 1e-10 would be fine as well). Something for later, 
though.

I left the label as "lower limit" for now. In R, the parameters are called 
min/max, but the help page uses "lower/upper limit" as well.

I've changed it to not accept any newlines (you can still use <input ... 
size="large" /> to get a multi-line input field). In most places, it just 
doesn't make too much sense. For plot_options, I added a hint to use '\n' to 
achieve multi-line labels. Of course, alternatively, we could use multi-line 
fields, but I don't like how it uses so much extra space (and breaks the 
tab-key), while this functionality probably isn't needed too often.

Of course, that's fixed by the above change.

You're right. It's pretty useless, right now. The little that is shown isn't 
very useful, and to resize it, you'll first have to resize the whole dialog, 
then adjust the slider (I've tweaked this slightly, now, but it's still not 
quite good). Definitely a broken UI. Problem is, I have no good idea on what 
to do about it, right now. Making the field larger would use more space on 
screen, and some plugins already take up around 550 pixels in the vertical 
(on this system, with not so very large fonts), so we'd easily get into 
trouble on 800*600 resolutions. Making the code window external would mean 
yet another window on the screen.

Ideas, anybody?

Thomas
