Bought, because I hate having multi-project work tabs open next to each other, no matter how hard I try.
Now, I can put them into silos, separate and distinct from each other, which fosters greater productivity and peace of mind, for me at least.
It's a wonderful start, and once Extensions are added it will take over as my one and only work browser as there are a number of previous Appsumo tools like TabExtend and Voila for example, that will work like a treat. Until then, I'll use it on a number of small side-hustles to see how they go.
One suggestion would be to make the billing timer optional. Right now, there are a number of internal projects which are not billable to anyone and therefore the timer is irrelevant, and to a certain degree, irritating.
