Topic: [HyperbolaBSD] Implementation notes and further development

Hello,

this thread is meant as collection of ideas for HyperbolaBSD and its further development. Before going further some notes and basic rulesets:

- Please only real possible ideas, not a wishing-concerto adding something complete impossible. To find the sensible line between possible or not: Something surely in BSD already implemented or nearing possible throughout code.
- Please no commentary only, except this is a clear relation to an idea brought into or some question. So you can at best point to the concrete posting with a link when you comment on it or ask a question.

Thanks!
