I just released a new SketchUp plugin. Its main function is to load other plugins. Here’s a screenshot of the main menu options:

Plugin menu for this loader

You can find a detailed description (and the download link) on the project page. Here are the feature highlights:

• Browse the main web plugin repositories and then load any plugin into SketchUp.
• Load a plugin from any location (works in a “locked down” computer lab, too).
• Load all plugins from one folder. This allows you to load plugins “on demand” and by category if you categorize them into subfolders.
• Have Ruby developer references handy. The developer menu items are all web links.

Give this plugin a try and let me know how it works. Download and comment here.
