I converted the popular skin Purple Beauty to B2evolution >= v2.4.1. This skin has always been a popular choice back in the 1.10 days. EdB coded the skin for 1.9. Original design is by Dieter Schneider. The skin is listed in the skins repositories where is gets a 2.9 / 5 vote.
When EdB coded the skin he left a few points to be improved. At that time I spent a lot of time on this skin and managed to solve most issues. That's documented in this forumpost. Of course all improvements are implemented in this version.
Skinshot -this is from the 1.10 version, but it hasn't changed that much-:

A long time ago I installed Greasemonkey and with the latest upgrade it survived after transition to Firefox 3.0.
Greasemonkey allows you to run javaScripts that you created yourself on somebody else's sites. That's the short explanation. Anyway, the script does not need to be included in the source as you might expect from a normal javaScript. You may want to change the background colour or the font size of an arbitrary site you often visit. Those are common uses, together with removal of certain elements most notably adds. You can completely restyle a webpage.
The main site Greasespot holds a huge collection of scripts. Installing a script is easy. If Greasemonkey is installed you only need to click the link to the Greasemonkey script to trigger an installer. You will see at the end of this post how that goes. Unfortunately I didn't find the Killer App there. I don't believe there is. So the use of Greasemonkey is in practice limited to things you make cy yourself. Luckily the huge script library is of great help there. You are bound to find a script that does 'almost' what you want.
In the Greasespot site you find a link to the Open Source (downloadable) book Dive Into Greasemonkey which is an excellent guide to get started apart from the fact that most of the examples don't run. The book is simply outdated. But worth a glance anyway.
For the B2evolution forums I wanted some hacks. One of them is available as Greasemonkey script. That is phpBB No Stretch. If a post contains a code with a very long line as can be the case with an URL the post itself becomes very wide rather than wrapping rhe long line. The phpBB No Stretch plugin for Greasespot does just that. It wraps the long line.
A very impressive plugin is IMDB Pirated Version It adds a bar with links to torrents of the particular movie from the page you're at. Have a look at this picture:

The line just under the film title is added by the script. If you click it it Ajaxes to the sites it gets its information from. Actually, this is a kind of Killer App.
You find the plugin at Sourceforge.
This plugin will adjust the size of an image to the container it's in. That way an image in a post will not exceed the borders of the post even if it's bigger. You simply install the plugin and it will do it's job. It relies on the image being spanned within a div with class image_block, which will be the case if you use the File Manager to add images to your post or if you use the [IMG] button on the toolbar.
example code:
<div class="image_block"><img src="image.png" alt="some alt text" title="some title" /></div>
This is code that's automatically generated if you insert an image using B2evolution. You can also add it manually to a post.
You might want to adjust the class. You can even use an ID. That's done in the settings of the plugin. You can even add several classes or ID's and it will cater for all of them.
Several images in this blog work with the plugin. You can click all images for a full scale version. That's done with the jQuery lightbox plugin. They work beautifully together.
The plugin is tested in Firefox 3, Opera and Internet Explorer 7.

My latest creaton is an edtor for the post/edit textarea. It will add a buttonbar and you can write your post and see the result in realtime. A WYSIWYG editor so to say. It's much like the TnyMCE editor. It's simply a different flavour.
All these buttons are usable, but 'll need to configure a few of them. It's even possible to upload images/files. For the rest it has all text edit optons like (obvious) bold Italic and colour. Oh, that's backgroundcolour, it has that also. You can more or less easily add links like this one to the website of FCKeditor. Let me add an image:

I also added the little brother of this monster to the Comment textarea, so do write me a comment. That one is actually to small, so I'll have to invent a medium. Luckily that's rather easy with the FCKeditor. Which buttons do you want for the comments?
Like I wrote in the B2evofoums, this is a work in progress. But do try it out and let me know what you want to see adjusted. I'll add it to BOPIT, so you can easily track new versions.
