[FEATURE_REQUEST] Update to Vue3 (Vue2 is EOL)

[jhalag]

Is your feature request related to a problem? If so, please describe.

According to vuejs.org:

Vue 2 has reached End of Life on December 31st, 2023. It no longer receives new features, updates, or fixes. [...]

We also strongly recommend current Vue 2 users to upgrade

Describe the solution you'd like

An update to Vue3 would be fantastic. The tooling is sharp. It will improve build times as well (which I believe I saw other issues about).

Having the composition API available for new widgets would be an added benefit. (I was looking to make a few for my own project)

Priority

Medium (Would be very useful)

Is this something you would be keen to implement

None
