Hello gecko and thanks for considering us!
We have had some discussion internally about your suggestions and here is the response:
1. We have not had this in our internal plans so far, but these are things we will add to our Suggested Improvements lists. Hardware Tokens might be fun. We have been thinking about a API in the future.
2. We do have more data available and we use it internally. I will tell developers to add it.
3. We are actively looking at the total usage of SSL in Runbox and we will take your suggestion with us in this process.
4. Updated Contacts and adding Calendar and Notepad is one of the highest things on our lists for new features development.
These are all really good suggestions. Apart from the first thing, they are all about or will soon be implemented.
Kim
