Hi!
At the 3DGS downloads page exists totally useless free example of the plugin for SED.
Can you (or Gustav Nordvall) update this example to show communication with SED as it does in the PanelEditor - ReplaceSelection, GetFileName, GetLine, GetLineCount, SetSelection, GetCursorPos and so on (DDE or what ever)? Or publish a header file to allow making more usefull plugins but not just "Hello from plugin!" one.
