Thank you very much for your appreciation and for the feedback!
The "Update All" button is a feature we are being constantly asked for. The main reason for this feature is not implemented yet is that there are many users who have 100+ active parcels. If they start spamming "Update All" button that might cause serious performance problems. In general there is no need in constant manual update, because all the parcels are always scheduled for automatic update.
We like your idea about parcel sorting and consider its implementation in the future updates!
