A great tool when it works.

I've spent a few months using this add-on on a daily basis and I can say it's very useful when it behaves as expected. Too often I'll navigate to a tab that hasn't been opened in a while, the workona re-direct link is momentarily there, and then it just disappears.
I have to search for the part of the title that was visible and hope search results pop something up.

Then there's the case where my workspaces disappear. If I leave it alone for a while (hours), it will eventually come back, but I'm prevented from utilizing workona which is a pretty big hindrance once you develop a tool like this into your workflow.

I've also seen duplication of workspaces as unsaved workspaces which is annoying.

All-in-all, workflow helps me get some work done, but it's extremely frustrating when it doesn't work.
While this *core functionality* is still so unstable, I simply can not trust Workona enough to be converted into a paying customer.

If you've talked to anyone who uses Workon, they've probably told you how bad it is. But you're probably skeptical, because after all, a lot of people seem to be using it. And the Pro and Business versions cost 7/month and 15/month, so people must be paying for something, right? Wrong. The free version is almost useless, and no, it's not worth 15/month. In fact, you'd have to pay me a lot more than 15/month to use this kludge.

It's true. Workona is a surprisingly bad tab manager. The reason it's used by a lot of people, is that its produced by a company with a certain business model. Quality, in the sense of the average user, is not that important to such companies. They need to convince the management of businesses that their software can improve productivity, when used in a certain way.

Also, companies at the mid level, not quite one person operations, but not Microsoft either, have the hardest time hiring good programmers, and they're the ones that need them most.

In sum, if you have a choice in the matter, don't even bother trying Workona; it's a waste of time. Almost any of the other options available will be a better choice.
