Did you notice the filter, that allows you to quickly find columns?

Creating new views from a custom view is a good idea. I'll see what we can do.

Any other suggestions to make it less clunky?

[Background for change]

We've wrapped up a 3 year initiative to migrate to a modern database technology (away from one from a company that went out of business years ago). In the process we had to rewrite dependent experiences like homebase & custom view management, using modern Microsoft Technology. That comes with benefits, and drawbacks. We appreciate your thoughtful feedback so that we can continue to iterate on improving the experience.

There will be more of that for TY21.. hopefully we can work with Austin and team to get very early access to get very early feedback on changes.
