There's a Gestures For Chrome
I can't attest to how well it works. I don't use mouse gestures.
I was using Chromium Snap Shots
That's where you get the most advanced features. I've just gone back to Firefox and I'm using Waterfox on my 64 bit machine. Most of the snap shots are surprisingly stable. I used the win32 zip files rather than installer. If you keep backups of your AppData\Local\Chromium folder and the folder that has the executable, you can back off to the previous version. It's important to do this because if the snap shot goes up a major version number and you try to use the local data folder with the older version you copied back over, you may get an error since the older version doesn't know what to make of newer settings.
The most important tweak I found is adding this to the shortcut target line:
if you don't use a render limit you tend to get about a 1/2 dozen chrome.exe processes plus one for each open tab and running extension. Maybe even more. Experimenting with the number you can decide what number for 'n' is best for you. To get back to default set n to 42(not documented but it used to be the default.) Once you run it with 42 then you can remove the setting if you want to remain at the old default.
One thing though, the built in bookmark sync totally sucks!! If you are not logged in, delete some bookmarks, then log in, it will restore the bookmarks you just deleted if the original set was in the store online. Totally brain dead. There's no Up and Down overwrite like they used to have. (If there is, you can't get to it before logging in automatically hoses you by syncing and restoring your deletions.) Nowhere near as good as FF SyncPlaces.
And no, you cannot use FF AddOns. You have to hope the authors also coded one for chrome.
I've gone back to FF as primary since 16.x. It does use a lot of ram, but it seems to launch pretty quickly to a blank page even if the disk is busy. That's the main reason I switched to chromium.
One Extension I do think is better in Chromium is Ginger Grammar Checker. It's the only one I tried that didn't fight with forum editor forms/applets whatever they call what I'm typing into here.
The good news is chromium does a lot on its own. You don't need extensions to play multi-media and it has built in search engine management. The bad news is if you run a lot of tabs, you'll be running a lot of processes. The setting I mentioned before helps a bit.
But it is fast and stable.
