I have pushed it down into the sac and it doesn't get in the way as I think I will use it in the future but even in Scottish winter, where I could use it to separate "dry kit" from a damp belay jacket eyc, it just seems to faffy.

I have the same sac and completely agree with all your points. Actually, carrying a rope under the lid is pretty much impossible due to lack of a suitable strap and the slipperiness of the material. I don’t love the supposedly one-handed main buckle either.
Otherwise really good, and ME’s repair service is excellent (crampon abuse that was above and beyond - and still fixed for free by ME).
