AWESOME. Just one suggestion! Rated 4 out of 5 stars

I'll admit it. When I found this, I squealed like a baby piglet. I knew it was EXACTLY what was missing from my current browsing experience since I often work better by including more relevant information in my work space rather than less. Ironically, what leads me to love this add-on also highlights its shortcomings as of right now.

Here's the thing: you can only have one instance of tiled tabs at a time. So if you're writing a paper, and you have 3 tabs tiled for research into your first supporting point, you're unable to tile other tabs separate from those, whether they're in the same tab group or not (probably because it tab groups won't make a difference to the code, just thought I'd fill everyone in). If this one hindrance was changed, the way I work would just... evolve. That would be a massive improvement on an already great experience! To make it easier to organize, perhaps tile sets could be numbered like tab groups are?

This review is for a previous version of the add-on (8.4). 

Multiple tiled layouts

The idea of having multiple tiled layouts at the same time has been requested by a number of users in the past. Technically, this could be done, because the Tile Tabs internal data structures are very generic. The obvious way to do it would be to have a different skin color for each tiled layout, but there are some design and user interface issues that would need resolving. However, his feature has not been implemented for fear of making the user interface more complicated and difficult to understand.

An alternative would be to use the Save Layout command to create a saved layout for each required set of tiled tabs, and then use the Recent Layout command to quickly switch between the tiled layouts.
