With this plugin you can switch to a totally different blog template when you are logged in to your wordpress dashboard. It's great for theme development as you can tweak the template online without breaking stuff for visitors. You can also use it for presentations, to show off various templates.
I have added a widget to make this easier. The widget will never be shown to anonymous visitors, and you can configure which user class it will be shown to. If you have editors you may want to exclude them from using it.
Since version 0.4.0 it is also possible to send your clients, friends etc. preview links. They won't need an account on your blog for this to work.
Why I wrote this? I posted a technique on how to use different CSS styles for logged in users, but I needed something more powerful. And I thought maybe others would like it too.
Better tag cloud:
I was pretty unhappy with the default WordPress tag cloud widget. This one is more powerful and offers a list HTML markup that is consistent with most other widgets.
Move WordPress comments:
This plugin adds a small form to every comment on your blog. The form is only added for admins and allows you to move comments to a different post/page and to fix comment threading.
Rhyming widget:
I wrote a little online rhyming dictionary. This is a widget to search it directly from one of your sidebars.
Snow and more:
This one lets you see snowflakes (or other, custom images) fall down your blog.
Fireworks:
The name says it all, see fireworks on your blog!
Q: I need the plugin to work for everybody, not just logged in users.
A: That's a feature I don't want to add, thanks for understanding.
Q: The preview links don't work!
A: Please check if you have some cache activated, that will most likely prevent the preview links from working. WP Super Cache only works in HALF ON mode.
Q: My site went blank when I used your plugin, how is that possible?
A: I've experienced this when I used invalid themes. Make sure the theme you choose with this plugin works before trying to activate it. If this happens to you while you use the widget try the following: Click the back button in your browser. The page should reappear, then select a theme you know to work. While you do all of this, the page should still be visible for your visitors, you can logout to confirm this.
The plugin may also fall back to the default theme, so make sure you didn't delete it.
