Show HN: A scalable clipboard manager for Linux

Especially the option to import from existing clipboard managers should help with adoption.

Some questions/suggestions:

- Why is the repo called "clipboard-history" and not ringboard, after the tool name?

- All `ringboard migrate` examples are explained with "imports x history". When documentation uses different wording from a command, it's often a sign that the command is not self-explanatory enough. Here for example "migrate" can be both to or from. Suggestion: Name the command "import"
