hey i tried this out quickly. pretty good. two thoughts:
1) is it me, or does it take two clicks to go from the plugin icon to actually accepting voice input?
2) android's voice search has both visual and audible cues to indicate to the user that it's actually picking up your speech, finished, and is now thinking about it. that'd be excellent.
1. To initiate speech input, there needs to be direct user interaction on that microphone icon. I wish there was a way for extensions to initiate it manually.
2. This is a bug in Chrome due to the extension rendering in a popup bubble and the usual speech indicator also being in a popup bubble, but it won't render as only one popup bubble at a time can be displayed.
