Okay, it's installed as per your instructions. I went into the configuration, and my settings were still there except it had "tags" selected as the column for tags instead of my "#lists" column. So I tried changing it but it won't remember my column selection. It keeps going back to "tags" every time I open it. I tried doing it one at a time but that didn't work either.

Edited to add: I can confirm that this happens with newly created lists as well, not just the ones I already had. Created "Kindle" list, assigned "Kindle New" to "#lists" column, assigned device. Clicked okay, reopened configuration and the column had changed back to "tags".
