How do I make suggestions for improvement to the softdevice stack?

I have some improvement I would like to see in the stack. How can I get these implemented. Improvements include:

1. Allow advertisement reporting events during connect scanning. Currently when a connect is in progress advertising packets are received and processed by the stack but they do not generate reports. There should be a option to enable such reporting.

2. Non-connectable advertising packets are limited to 100ms (<10Hz in practice). Remove this limitation as it adds nothing to the abilities of the stack.

3. Dynamic advertising cannot be implemented well in the current stack because the stack does not have a "transmitted advertising packet" callback (which seems like it would be trivial to add) and because of the 100ms limit above. When scanning, connecting and advertising at the same time there appears to be no way to determine that an advertising packet was sent so that a new one can be loaded.

4. The 100ms limit also means that if you want to cycle through even 2 packets your net rate is 5Hz, if you have 10 packet the net rate would be 1Hz. There should be a way to instantly send advertising packet so that the "transmitted advertising packet" callback can send dynamic packets.

OK, I've missed this detail. So it's only about the time between sd_ble_gap_connect function call and incoming BLE_GAP_EVT_CONNECTED event. I'm afraid it still makes sense because once you said to lower (LL) stack to connect you should be not interested about further scanning events. If you are you should enable separate Observer (or Central) role, shouldn't you?
