The Lorby Scratchpad has been released as version 1.0.
This app synchronizes an external app window with a message window in Prepar3D V4.x. You can take notes on this window from within the simulator or add complex text snippets to it on the app window.
Furthermore, the Lorby Scratchpard includes an Editor for the Kneeboard files that are associated with your aircraft. You can add any text or pictures to those files using a simple HTML editor window and access them through the standard Kneeboard feature within your simulator.
The Lorby Scratchpad is a freeware tool available on the DOWNLOADS page.
