Current syntax highlighting only colors keywords. Putting type references into a better scope would be beneficial.

Installing missing tools like k3 language server would greatly improve user experience.

When displaying recommended extensions, the list is empty.

We should probably do not recommend extensions, if we don't have any.

The extension supports auto installation and update of NTT.
The problem is, if the NTT update is failed, extension will not start the installed NTT or the NTT in $PATH.

	if (conf.get('server.update')) {
		try {
			await nttDownloader.downloadServerIfNeeded(status);
			// Ensure that start script can be executed
			if (isOSUnixoid()) {
				child_process.exec(`chmod +x ${installDir}/ntt`);
			}
		} catch (error) {
			console.error(error);
			vscode.window.showWarningMessage(`Could not update/download TTCN-3 Language Server: ${error}`);
			return;
		}
	}

Should remove the "return" in catch(error) block to ensure the start of existing NTT.

sometimes 'go to definition' failed, if manually open the file function defined in，'go to definition' success
