I would suggest that you add “intermediate” or something similar to the Victron expertise tags. Speaking for myself, I wouldn’t say I’m a “beginner” but neither would I claim to be an “expert”. I’m definitely not a “professional”.
Some tags don’t appear unless you select a particular tag. That would be fine, except the hidden tags would still be relevant regardless of the selection. I can’t think of an example off the top of my head.
