have 'OR' instead of just 'AND' rules
current rules are 'AND', limiting rules possibilities. Although it is possible to create multiple rules to achieve the same outcome, have one rule with 'or' has much better semantics and minimises the number of rules

This is the same wrong functionality in Apple Mail as well. I have a lot sources that interpreted the same was. (delete or move after two days for example) In apple mail I set a dozen rules to archieve this. This is because I need to select "all" option at the top and give only one email source AND the day count I would like to have the action done. So it would be great to have more complex rulesets (sub sets).
