Some observations on flight performance

Hello team, first of all, congratulations on the release of 787-9! I am a PC user and I started owning both 787-8 and 787-9 a couple of days ago. I like both aircrafts very much and really appreciate your team in putting the efforts to make the aircrafts as realistic as possible.

Visually I noticed a few issues when flying both aircrafts and I am not sure if they have been raised / answered before, and if these are on the part of Asobo/ WT instead: -
1/ When on AP, tracking LNAV and making turns, sometimes the plane will overdo and then correct itself, for a few times. Generally it is still able to track the LNAV but just the plane doesn't make then turn smoothly
2/ Sometimes the warning "bank angle" would be triggered when making turns. It is not necessarily triggered on the most acute turns - I think it's related to #1 as even when the turn isn't most acute the alarm may be triggered when the aircraft first overdoes the turn before correcting itself.
3/ The climb performance does not resemble the Simbrief closely - generally the aircraft climbs too slowly compared to Simbrief's output

Furthermore and separately, for the EFB, with the makeshift BA EFB implemented, how can user calculate takeoff performance as the default EFB is overridden? Is there a way to switch back/ forth the default and BA EFB?

Many thanks and I do hope the above help your team in further refining the brilliant products!
