Aha! Thanks to @paulmyatt ( http://ow.ly/iWem ) I have discovered how to add a GoogleVoice gadget to Gmail’s sidebar. Yay! I also then figured out how to add Gizmo5’s VOIP gadget as well – so that now, I can see my GV voicemail’s in Gmail, send/receive SMS there, make phone calls with GV, and receive phone calls to my GV # via the Gizmo5 widget. Sweet… (It’s also possible to add both of these to iGoogle, but the URL’s are slightly different…)
Part of the reason this is possible is Google Labs – a feature most Gmail users probably have no idea about, but which is awesome. You have to go to “Settings” and then to “Labs” to see all the possibilities. There are some great ones. The problem is, they could disappear at any time, but aside from that… Google Calendar, Google Docs, the ability to have chat on the right, “mark as unread” button, send SMS in Gmail chat, and, for the purposes of this post: Add any Gadget by URL… Very important! Once you have enabled that, you can enter the URLs below to add either GoogleVoice and/or Gizmo5 gadgets to Gmail…
Oh, disclaimer: the Gizmo5 gadget is too wide for Gmail, but with the side-side scrollbar, it’s still usable… Enjoy!
