I spotted something that looks like a problem with rendering emoji. I wrote it out here but they didn't display correctly when I submitted the post. Here's what they looked like to me:

The forum software displays those three examples like this, which might be a clue to the problem. Note the slight color change in the last example:
💻 Inbox Zero 💻
🧑💻 Inbox Zero 🧑💻
🧑💻 Inbox Zero 👨💻
I access Legend via the desktop app on two different machines; one Win11 an one Win10. They definitely use different emoji sets (both from each other and from Flarum), so that's probably where this comes from.
