Hi,
We have a problem with the dependencies editor when it's a big project.
When I open the picker it takes a lot of time until the list is shown.
please see the video below when the project contains more than 1600 rows:

Yes this is an issue since the List has no virtual rendering capabilities. We'll investigate swapping that to a Grid instead. https://github.com/bryntum/support/issues/3833
