Hi there @mjpraxis!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

This will be, sort of, fixed as part of this PR:
umbraco/Umbraco.CMS.Backoffice#2065

As v.14 comes with a Extension Registry, this has allowed us to finally move Custom Views into code, making them a Backoffice extensions them selfs.

Therefor it will no longer possible to pick a file via UI, this is done in the same way s any other UI extension.

I don't know if it's just me, but I feel like there is some confusion on how this is handled now for Block Lists.

In v14.2 Block Grid has a "Custom View" section under the "Advanced" tab

But Block List has no "Advanced" tab or "Custom Views" section

Documentation seems to be the old AngularJS way
