Of course, takes too much to unchain them and re-order (gets chained while doing this or the order gets messed up), and it's a must for fights and sneaking around.
Then I go to camp and when leaving they are joined again. Unchain them again one by one. Then adjust their order, because can't select same with F1 to F4 if they aren't in the right order. Then link them again before entering a door that goes into a different instance, otherwise only the selected enters, which is fine sometimes but not always.
Best would be to give us party related customizable buttons:
1. link them all, while keeping them in the order I set them manually before (my char is F1, fighter is F2, cleric is F3, wizard is F4)
2. unlink just my char, keep rest linked, still keep the order I set
3. unlink all, but still keep them in same order F1 to F4
