I have some messages marked as 'Important' and others as 'Actions'. But I can't see which folder contains such messages unless I search for those in every folder. Therefore I think it would be nice to report in the folder list the number of flagged messages in their column type. Reproducible: Always Steps to Reproduce: 1. Flag a message as Important. 2. Try to see on the list of folder which one contains an important message. Actual Results: The user needs to search on each folder for special/flagged messages. Expected Results: A column in the folder list containing the number of messages when not zero. It could also change the colour of the folder to highlight when some message is flagged.
