Which features matter most to you?

Whilst doing some research on the existing market of 'productivity apps', I came across yet another 'X best to do list apps of the year ahead'. But this one was interesting because it provided a little insight into the features that were important to Zapier users by categorising the apps as 'best for X action':

It would be great to have a view on what the most important features are for _each_ member of our team. After all, we're building this for ourselves first!
