I see that is copies a shortened version of the link to your clipboard. For example this link:
https://kbin.social/m/kbinMeta/t/177112/kbin-project-management-costs-financing-future-plans
is copied as:
https://kbin.social/m/kbinMeta/t/177112
Is that all it does?
So a permalink. Sounds like the menu item should say “Copy Permalink.” “Copy URL to Fediverse” makes it sound like if I click that link it gets exported, auto-posted, or sent to other fediverse instances automatically.
I imagine it’s just poor translation. English isn’t Ernest’s first language, and although he speaks it very well it’s very clear from looking at some of the less-commonly-used parts of Kbin that some terms seem to have been translated directly from their original Polish without strong consideration about whether they remain as easy to understand their meaning.
