Panda Search Engine News beat me to the "google christmas presents" idea...
Here are mine anyway:
1. Put http:// back in the urls
Like many avid google users I use the google personalized search feature, this has benefits in that you are able to look back at what you searched for and found, but it has the disadvantage that the link you click on in the search results isn't the real link. It redirects through google's tracking servers.
The problem is now that you can't look up a site then right click copy url and paste it into an email. You can select the url under the result and copy and paste that, but you have to add your own http:// to get the mail client to recognise it as a link. Since Yahoo also seems to do that same thing there may well be a very good reason for not displaying the http:// but it would be good to atleast hear it so that I can think of all the people I am helping each time I type http://
2. Speed up google analytics
3. Make Picasa Web Albums manageable with picasa
When I heard about picasa web albums I was excited. This was going to mean I could create and manage albums in picasa and publish them on the web. Hoorary! The reality
left something to be desired. Picasa basically is just a tool you can use to upload files to picasa web, what we really need is something that will keep the same albums synchonised, eg. you say put this album on the web and as you add or remove files they magically appear in the right place on line.
4. Add a "grab contacts" button to Gmail
I often get emailed other peoples email addresses, or see people I need to email cc'd into an email I get. I would be great if there was an easy way to add these people into the address book.
5. GCal Outlook Sync.
People have been asking for this for a while, and some people have even developed some work arounds, but none of the ones I've tried work reliably for me. I think this is something google need to develop before Google Calendar really takes off in the business world.
Update: Syncmycal provides an excellent and free solution for this! Thanks Vaibhav.
Have a good break, and come up with a whole lot of better ideas to do next year...
Update: Matt Cutts likes my list!
