<div dir="auto">Not really used any more. We used to encode the
cylinder number in the flags (because libdivecomputer didn't
give it any sane way), but now it's just legacy noise that
doesn't get renumbered. So it was the first cylinder for the
vyper, and it is still flags=1 for that one, and it was the
second cylinder for the OSTC, so it's flags=2 for that one.</div>

Remember that these approaches towards non-used cylinders need to
take into account the setting in Preferences->Graph: Misc. Show
unused cylinders in equipment tab.<br>
I will eventually have to write about this in the user manual. So if
the management unused cylinders is easy to explain, that will really
help.<br>
I will do some testing of this using some dive plans, once the patch
has been pulled into master. It appears pretty useful.<br>
Kind regards,<br>
