Version 1.0
A remake of my old alpha that I released on the Simutrans Forum this new package now offers smarter completions and complete syntax highlighting, including old deprecated values and parameters.
Deprecated values that still work should be shown differently from deprecated values that will break build, it depends a lot on your theme. You can get a hint of what's the problem with the deprecated option by hitting Ctrl+Shift+Alt+P when hovering it, the info will be shown in the status bar.
