Everything gets put into the pockets of my SeaQuest ProQD BCD. Nothing dangling. Streamlined.
--------------------
All of the above items permanently reside in the pockets. Once in a while, I'll take stuff out and rinse it off and dry it before restowing, but much more often I'll just rinse the BCD and everything together while leaving everything in the pockets. Gear doesn't do you any good if it isn't available when you need it.
---------------------
+1 here. This particular BCD has clips inside the pockets, which I have found very handy.
