I easily did what I wanted with it.
One feature request is to make an option to run plugins inside.

Thank to this plugin I can use old national font at my site and it looks very nice!
Upon my experience you have to check all site pages in all browsers to proof the proper look for all replaced styles. Once you faced some misalignments, first of all check component or module to find if it is properly coded.
Also, author's response is quick.
Good job, Pete!

Some time ago I tested this very plugin for one of my sites and found it was not working for unknown reason.
But for another site it works excellent! I couldn't force to work any other redirecting extensions but this really works in any browsers flawlessly!

I'm testing this plugin since version 2.00. But in fact it works only for css for all my sites.
When I select "GZip JavaScript and CSS" option and NOT "Optimize JavaScript Files" then only css-files are compressed.
When "Optimize JavaScript Files" is set to YES, then javascripts are really combined into the only file but stop working.
Unfortunately, this new version also doesn't keep javascript working though speedup page response by 10-15%.

This is an amazing extension I've been not aware of.
What a pity that it doesn't support SEF-links...

Must have extension!

Work flawlessly with core SEF set to OFF.
When SEF is ON, expand/collapse behaviour of trees become unpredictable.
I noticed that with core SEF set to ON java-script generates many cookies instead of one.

Another minor issue is that plus/minus icons disappear when browsing DocMan contents.

In order to solve this issue I added
additional leading slashes to pathways to images in docmantree.php like this:

'/modules/mod_jdmtree15/jDMtree/images/docmantree_expand.gif'
instead of
'modules/mod_jdmtree15/jDMtree/images/docmantree_expand.gif'

Now everything is fine with icons.

I hope Josh will solve the first problem easily in near future.
Best wishes!
