For many people, the Flash media uploader does not work properly. I found it frustrating that this was the default option, requiring an extra step to get to the Browser media uploader.
This plugin works by hooking into the ‘flash_updater’ filter and setting the variable to false. This makes it seem to WordPress that the browser doesn’t support flash. Because of this, the option to switch to the flash version isn’t shown. Future versions may work around this if there is a need for it, but I would imagine that if you don’t want flash, you don’t want it at all.
There are also no setup options in this version. It is turned on by activating the plugin and turned off by deactivating it. Easy, peasy!

FlashFreeze

This plugin simply blocks the Flash media uploader and allows you to use the Browser media uploader by default.

Want to use shortcodes in your sidebar Text widgets? Don’t want to have to update the functions.php of the 
theme to achieve this? WidgetShortcodes comes to the rescue. This plugin simply hooks shortcode_noautop and 
do_shortcode to the widget_text filter to make this happen. It keeps on working even if you change themes.

WidgetShortcodes

This plugin adds shortcode handling to the widget_text filter so that shortcodes can be used in Text widgets
on the sidebar.
