/* Things to test.
 * - Feature
 *   + How to check that it works.
 *
 * - Proper stores displayed
 *   + Skip stores that don't support subscriptions
 *   + Skip disabled stores
 * - Changing subscription status
 *   + Select single folder, double-click row -> toggled
 *   + Select multiple folders, press subscribe -> all selected folders end up subscribed
 * - (un)Subscribing from/to already (un)subscribed folder
 *   + Check that no IMAP command is sent
 * - Switching views between stores
 *   + Proper tree shown
 * - No crashes when buttons are pressed with "No store" screen
 *   + obvious
 * - Restoring filter settings when view switched
 *   + Enter search, change view, change back -> filter checked and search entry set
 *   + Clear search, change view, change back -> "all" checked
 * - Cancelling in middle of get_store 
 *   + Enter invalid hostname, open dialog, click Close
 * - Cancelling in middle if listing 
 *   + Open large directory, click Close
 * - Cancelling in middle of subscription op
 *   + How to test?
 * - Test with both IMAP and NNTP
 *   + obvious
 * - Verify that refresh view works
 *   + obvious
 * - No unnecessary tree rebuilds
 *   + Show All folders, change filter with empty search -> no tree rebuild
 *   + Converse
 * - No out of date tree
 *   + Show All Folders, change to filter with a search -> tree rebuild
 * - Tree construction logic (mostly IMAP-specific terminology)
 *   + Tree is created progressively
 *   + No wasted LIST responses
 *   + No extraneous LIST commands
 *   + Specifying "folder names begin with" works
 *   + Always show folders below IMAP namespace (no escaping the namespace)
 *   + Don't allow subscription to NoSelect folders
 *   + IMAP accounts always show INBOX
 * - Shell interactions
 *   + Folders are properly created / delete from folder tree when subscribed / unsubscribed
 *   + Folders with spaces in names / 8bit chars
 *   + Toplevel as well as subfolders
 *   + Mail Folder Cache doesn't complain
 * - No ETable wackiness
 *   + Verify columns cannot be DnD'd
 *   + Alphabetical order always
 * - UI cleanliness
 *   + Keybindings work
 *   + Some widget has focus by default
 *   + Escape / enter work
 *   + Close button works
 */

/* FIXME: we should disable/enable the subscribe/unsubscribe buttons as

 * changes, so when the user double-clicks it (eg) the buttons can
 * (de)sensitize appropriately. See Ximian bug #7673.
