tools are personal. what yours "solves" is probably an unknown unknown to others, and slamming a personal choice for neglecting that problem just creates distance. new tools are a big ask. imo convincing someone to try yours is really about understanding what they value in theirs. it's empathy.

one tip i give folks starting with anywidget: invest time in understanding ESM. get comfortable spotting what is, and ~especially~ what isn't. tooling lets us write plenty of code that no JS runtime could ever execute, and it leads to a ton of indirection and misunderstanding for beginners.
