It's nearly impossible to get the triggers in their initial view, cuz many of optimization programs delete the .w3g file (mb I'm wrong), where the info of trigger structure lays. You don't see units in editor in any map, if its deprotected with the use of xdep. Btw, xdep is also optimising map. It makes it load faster & it also moves all trigger events to the one function. Btw, there is a line in .ini file, which allows you to keep the temp folder with the all files, that makes the map open in editor faster, but it's initially turned off.
It's perfect guide for noobs in editor, because it's only using programs. You can get more info from map with units, if you open the map by yourself. But it's very simple and some pics make it look great,
