I have the following feature request: Add the ability for categories for the accounts. Use case: For each website where I register to, I use a separate email adress. To be able to send email accordingly, I have an email account for each in `claws-mail`. This results in a lot of accounts which become difficult to keep track of in `claws mail`. So I suggest a feature that allows to create account categories and assign each account to zero, one or more categories. Regards!
