• Rename
• Delete
  • This removes the need for the inline delete icon.
• Duplicate?

Also:

• Remove unnecessary file watchers. They will have been replaced by these new built-in buttons.
  One could call that a regression, because right now it does work based on the actual file system, but it's incredibly wonky and I don't like it.

  	Directory(p.join(projectPath, "web", "maps", prevMapID));
  	if (mapDataDir.existsSync()) {
  	mapDataDir.rename(p.join(projectPath, "web", "maps", nextMapID));
  	}
  	} else {
  	//could not get destination, so we nuke everything and re-add it all
  	maps.clear();
  	for (final FileSystemEntity map in entity.listSync()) {
  	if (map is File) {
  	maps.add(map);
  	}

  	});

(Probably requires maps list to become a provider.)

I tried adding an actual Right Click functionality, but that proved to be more challenging than I thought.
For the time being, a simple kebab menu on the right will suffice.
