My biggest issue with Thunderbird is the Quick filter search I have thousands of emails in one folder and it can block the UI for a while when making a basic search :-( . And it's also not correct, it won't show all the results, so I have to resort to using the real search which is clunky to use on a daily basis. If only they could fix this ! The UI is great already, it doesn't need much work
