Title explains it well.
Add another button on the left hand menu. This one would be a simbrief page, where you could create or edit flight plans. Same functionality as the web version, but built into the application.
Would be usefull to not have to juggle so many different webpages/applications.
Could even just open the simbrief webpage in the charts app. Basically have the charts app function as the web browser.
Thanks
