No way to "load more email"
Expect: I can load more, older emails. As much as I want dekko will download them and keep them for offline consumption
Actual: there seem to be two notions: X how many emails are shown Y how many emails from the past are downloaded at the bottom of the email list there is a button that allows me to increase X, until it reaches Y afterwards I cannot get more older emails
Unclear: we probably want to limit the number of emails in the cache somehow. we probably don't want to simply only ever add emails and let the set of offline available emails grow infinitely (we're running on a mobile platform!).
But maybe, this can be seen as a separate issue? So, this issue would focus on: load more. A separate issue could deal with: remove really old emails from the local cache after some time...
