This app is very nice  but still misses one feature  may be you can consider this for future releases. It will be very good to have the possibility to change the poll frequency depending on time  something like in samsung mail client top hours (working hours) - once in 3 min  during normal time once in half an hour (the polling time are just examples). Now it is possible to set the polling time only globally not depending on time frame. Thanks  and good job!
