Great app!

Overall, I’ve learned to really love this app. It’s fast and responsive even when handling multiple email accounts. Especially compared to the excessive slowdowns I’ve experienced in the Mail app under Yosemite. It’s easy to find all communications from the same person/business and delete an entire thread at once. However it could use a few improvements: When right clicking a thread it gives options to Remove star from messages, move all messages to spam or trash or archive, but you can’t selectively delete only certain messages without doing it one at a time. It would be great if you could star the ones you want to keep and “Delete all but starred messages”. Or at the very least allow you to shift-click to select multiple emails within a thread. Right now it only allows you to select multiple threads.
