Useful in general, could use some improvements Rated 4 out of 5 stars

It works as advertised, gets the job done and has some nifty advanced features. Kudos on that.

But, IMHO, the less polished part is actual snippet insertion (what you do most of the time). It provides a number of methods but most of them fail to feel really comfortable:

- Context menu forces you to browse several levels of nested menus.
- Keyword short-cuts force you to assign a key to every single clipping you want to use and you'd better learn it by heart (there's a help dialogue with the key list, but it needs to be invoked manually and has to be dismissed before you can actually insert anything).
- Toolbar button is possibly the best method, but it's fairly counter-intuitive to insert snippets from the Clippings Manager dialogue by double-clicking on their names, esp. when the dialogue necessarily covers the target text box.

Creating a new clip is almost easier than using it afterwards.

Last but not least, a "Sort by name" feature in the folder content-menu in Clippings Manager (just like Firefox itself has in Bookmarks Manager) would be really handy.
