For the autocomplete you can already select which syntrax you want to use (

For the seperate syntrax highlight, i may add that to the Design feature todo list.
Maybe each config a custom style?
Do you mean BasicPawn should automatically switch to the new syntrax when "#pragma newdecls required" exist? Yea, seems legit, i'll add that too.
And i'm adding more compiler options later on. In the current version the only way to set arguments is to use shell. (

Edit:
I've tested BasicPawn on Linux Ubuntu x86 using Wine (Installed .NET Framework 2.0 using Winetricks), it's actually working pretty well and stable.
