I started using this a few months ago. It definitely helps a lot, but it can still break the workflow.
Using OSX, when I click on a link inside Mail, it opens it in Chrome using the last used user. It's annoying when it's the wrong user. You still need to switch users and reopen the link in Chrome.
This is why I use different browsers for different accounts (Chrome, Safari and Firefox are generally all fine for regular web use) and Choosy (http://www.choosyosx.com/) to prompt me which browser to open the link in.
It also allows for binding certain URLs to specific browsers.
I have the same problem, as I have a personal and a work Google account. Chrome can sometimes ask you if you want to switch accounts, but in the end, I use Firefox for personal stuff and Chrome for my work.
To sync to Google Drive, I use Syncdocs http://syncdocs.com which is an enhanced Google Drive sync app that enables syncing multiple accounts at the same time.
I think Google wants each user to only have one account, which makes it better for them tracking ads.
I'd recently looked into ways to cure the pain of multiple google drive accounts running on the desktop app. People spoke highly of CloudFuze and InSync, but their support forums were filled with really awful error reports about random file deletions or endless file replication.
These services sound like a syncing layer on top of a syncing layer, which seems prone to errors.
It's a fucking godsend, every computer I have has 3 different Chrome accounts on it, all short cuts on my tool bar.
On windows at least it is trivial, extremely trivial, to switch between them. You will generally be in one of the modes, for me these are "their company", "my company", "personal".
Whichever one you used last will be the one that receives the "open internet" command. So if you are in "their work" mode, reading your emails in their email client it will open the google doc in the right context.
For you your workflow is somehow broken, for me that's exactly what I want. If I'm in "their work" mode, I want all browsers to open in that context. I'm not expecting them to be psychic. That means 95% of the time it just works because you are already in the right context. The other 5% you get used to very quickly. If I open up my personal email account, I want any next links clicked to be opened in that context.
Added bonus, it's great for every SASS not just just google accounts.
Would be cool if it could detect which users had access to the document and switch to the most recently used of those to open the link. Not sure if that can be done securely though.
