While some of the proposed enhancements look useful and I look forward to your next version, I am finding the current version (1.0.2 beta) very useful.  I copy a lot of stuff and paste it into eMail.  Being able to strip unwanted formatting or change capitalization on the fly is very nice, as is the ability to correct Caps Lock mistakes or the unwanted formatting changes that Thunderbird sometimes makes.

Simple. Easy. Useful.

Another suggestion:

When pasting text like a file name, provide the following options in the menu or the settings dialog (Expenses from 01/04/2011 to 15/04/2011):
* Remove invalid characters (Expenses from 01042011 to 15042011)
* Remove invalid characters and spaces and capitalize any letter that immediately followed a character that was removed (ExpensesFrom01042011To15042011)
* Replace invalid characters with X, where X could be specified via a setting (Expenses from 01_04_2011 to 15_04_2011 or Expenses from 01-04-2011 to 15-04-2011)

Thanks for the handy application, Ananad.

I would like to suggest an additional format.  When you copy a link from an article in a browser (eg, Chrome), you get something like Sample #1 below.  When you simply paste it into an email client (eg, Thunderbird), it changes your formatting because of the embedded class and style attributes and the span tags.  It would be nice if you could eliminate all attributes except href and all tags except <a> and </a> (see Sample #2).
