I'm trying out tiles and and I love the concept, but as I'm noticing is a rather irritating trend with Stardock Software, They are all fantastic ideas that lack key custimzation options needed to make it feel good or apply too wide use cases. (Such as Groupy's inability to customize shortcuts, SpaceMonger's lack of a TreeSize style tree-view, etc.)
Tiles 2 previews are absolutely HUMONGOUS. I don't see any way to adjust how large the tiles are, making it necessary to scroll through windows each and every time I wish to use them if I'm working with more than...3 windows. And I have the bar set to Large too. I also didn't see options like how to display tiles or organize them by last use.
It's a great idea, but it falls short of the Taskbar just based on the how poorly it uses its screen real estate.
