It's really great! I've tried v1.6 earlier today for the first time, and it's honestly the first editor (plugin for an editor here actually) that replaced AMXX Studio fully for me. There would always be something I miss in other editors, but this one has it all.
However, I've found a few bugs today.
It doesn't want to detect functions (or just natives?) that return a tagged value. For example, the following line of code isn't detected by the parser and isn't added to the function list for autocompletion.
native WSResponse: WS_CreateBinaryResponse(const content = "", length = 0);
However, it strangely works for the stuff that's already in AMXX, like Tries and Arrays. Can you please look into that?
Also, functions that retrieve a parameter by reference have the "Params:" field in a pop-up broken. Like menu_item_getinfo() for example. It stops parsing right at the ampersand symbol.
