Will there be a database for all functions in the game (Like Amnesia)

[Javist]

Updated it to be correct, only the option in the settings that had changed name.

Not this only has changed
1. This suggestion "If no color coding, it can be forced in View→View As: C++" is not valid anymore, as there's no such element in View.
2. "ctrl-left-click on #include, variables, functions etc will open/move cursor to their location." seems, doesn't match reality, by default this action will taken by clicking alt+left mb. This can be changed under Global Editor Preferences -> Tweaks -> Code navigation key.

Got it work finally somehow.
Code completion is working, but the code coloring is partial/tearing. Well, glad it at least working :3
