Being able to save the output window to a text file would be convenient.
Currently CTRL+A , CTRL+C, then paste into a text file is the only way to save the windows data.
This would join the Addin_WriteOutput and Addin_ClearOutput macros.
Alternatively if programmatically the output window could be sent to the system clipboard then an addin could save the clipboard to a file. Perhaps Addin_ToClipboard which would take a tab handle and send that tabs data would be more generic.
