This is a feature request. I'd love to see Google do this but I imagine this might also be possible via a third party service built on the gmail api.
I will often log into my gmail account on a conference room display in order to find a document that I want to load on the big screen. I do this a lot and I see many others do this frequently. Many entrepreneurs will do this when they come to see us. They will log into their gmail on the conference room display, they find the presentation they want to make, and then load that on the display.
The problem with this move, of course, is you briefly display your entire inbox to everyone in the room. That is suboptimal. But even so, I do this all the time. I've gotten pretty good at jumping into the search box quickly and running the search in order to get out of the inbox display.
So here's what I want. A simple app I can use that runs at something like gmailsearch.com. I go there, log into gmail, and then do a search on my inbox without having to reveal my entire inbox first.
It is possible that this feature already exists. If so, please tell me how to do this. I can't figure it out and I have tried. If this feature doesn't exist, it should.
