Workona is a chrome tab manager that I use to manage groups of tabs into contextual workspaces. Each named space has a list of active tabs and you can also designate lists of resources which can be sites, google drive folders etc.

One cool feature if workona is that every workspace has its own unique url. When you open the url from anywhere on your device, chrome will go into that workspace and all of your tabs will be set accordingly (and any tabs you had open at the time will be backed up into another open space in the ui).

This way, I can use the url field in RTM (I use the desktop app so it isn't part of any of my tab groups and always available) to be able to jump to a given context from a task.

For instance, on the first of the month, I have a repeating task for rent. The task opens my "rent" workspace that has a spreadsheet of expenses in google docs (rent, utilities, insurance, etc.), an ongoing email thread with my roommate for communicating this month's expense breakdown. And all of the portals I pay rent/utilities in case I need to check those bills for adding into the expense spreadsheet. These all get opened in a single click (or via the shift+U keyboard shortcut) in the RTM interface!
