The vanilla game places escalations left, without the group. That's why I added them there. I also prefer escalations neatly grouped together, even if they are based on different base missions. I agree that it initially feels a bit weird for Paris with its many ETs, but after scrolling through the menu for testing I grew to like it.
I'm open to adding an option to sort them into the regular flow, if others will not grow to like it, though.
Haven't checked out live tiles, but the menu can access metadata and it would even be possible to automatically generate that for escalations. So probably possible, but I don't know if the live tiles you refer to are working nicely this context. Might look into it.
