Indeed. Unfortunately, I can't come up with anything to change everywhere, 
right now ;-). Seriously, I've had a close look at some of them, and a glance 
at all each one of the PHP files, and I just can't find anything to complain 
about.

I'll take another look on Sunday, and if I don't find anything then, either 
(or somebody else finds somthing until then), I'll move them to the 
distributions .pluginmap, making them "official", then.

Yes, I've been thinking along those lines, too. One problem is, that you'd 
typically want to include a whole number of "blocks", in this case:

1) some <logic>
2) the "CLT Samples" frame
3) the right column
4) preview and plot-options
5) the hist and ECDF-tabs

The problem isn't that those 5 blocks are anything complex, but in order to 
place the distribution parameters frame directly in the center, where it fits 
nicely, I think all the rest would need to be split up into this many parts. 
If we ever were to offer a wizard interface to these plugins, the problem 
would multiplicate.

One idea I have right now is to use your <include file="..."/>, but this file 
would define different "snippets" that can be placed at different places:

<include file="common_elements.xml" id="common_elements"/>
<logic>
	...
	<insert snippet="common_elements.logic"/>
</logic>
<dialog>
	<tabbook>
		<tab label="Parameters" >
			<row>
				<column>
					<insert snippet="common_elements.samples"/>
				</column>
...

This would reduce the number of files needed, and at least keep all the common 
elements in one file.

On the other hand, in this case, perhaps we'd really want to do it the other 
way around: Have one common "template"-XML file, and this file will simply 
include the frame of distribution parameters at the right place. Difficulty 
is how to "know" in the code, which distribution parameters need to be 
included.

Perhaps we can mimick what we just did for the PHP files: E.g. the 
plot_weibull_clt.xml would look like this:

<document>
	<snippets>
		<snippet id="logic">
			<set id="plotoptions.default_main" to="Weibull"/>
		<snippet>
		<snippet id="parameters">
			<frame id="frame_weibullparam" label="Weibull Parameters">
				<spinbox default_precision="1" type="real" id="shape" initial="2" min 
="0.01" label="Shape" />
				<spinbox default_precision="1" type="real" id="scale" initial="1" min 
="0.01" label="Scale" />
			</frame>
		<snippet>
		<snippet id="note"><!-- empty --></snippet>
	</snippets>
	<include file="plot_clt_template.xml"/>
</document>

plot_clt_template.xml would define all the common stuff, and, insert the 
defined snippets at the right places. Now how to set the dialog caption, 
correctly? No good idea on that, yet. But I think we may be on to something.

Also referencing this mail in the TODO file, so I can easily look it up again, 
later.

Regards
Thomas
