The "picking" control currently supports Projects, Shared with me, Public Favorites, and My Favorites, which are browsed in an expandable tree. As the number of projects becomes large, this has a few problems:

• Apparently it doesn't do paging, so if you have more than N projects (some number between 100 and 1000) it only shows the first N and the rest don't show up
• Project contents are probably sorted by last modified time on the project record, which doesn't really reflect recent activity
• "Shared with me" is unsorted / has an non-obvious sort order
• The control only shows about 10 lines of text at a time

The workaround reported by users is to "favorite" a project, so that it is possible to find, but this is awkward and requires additional steps.

Proposed solution: incorporate the top Search / Advanced Search into the picking control. This should be available for the dialog boxes used for picking projects, collections, and files or directories within collections.

When search is in effect, the content is limited to projects (and/or collections, when picking Files or Directories) that match the search. Projects and collections that are matched can be further expanded to navigate inside them.

For this this ticket, search/filtering should not extend to navigating/searching collections. Navigating collections should continue to use the existing expandable tree behavior.
