Order of sitemaps?

I am using BasicUI heavily based on custom made sitemaps for each room. My by far most common use case is to open the app on my phone, select the appropriate sitemap and do my task. To me, this seems to be superior to having a big sitemap with nested groups or frames - if not for anything else, then to keep the files small and easy to manage.

What I did not get at all is what determines the order of sitemaps, be it in the sidebar of the app, or in /basicui/app?sitemap. In my setup, the order seems to be absolutely random. Is it possible to influence it?

I don’t think so, at least not with openhab 1, most if us are left with thousands of lines in one sitemap.
