Thank you guys for asking.
But there is no new "Trail" theme. Playing withsome features I made a new colored theme for mainly private use with OpenAndromaps and Locus (store) maps for hiking, because only the Locus maps support the hiking symbols.
There is no support for Atlas and p. e. Oruxmaps today. And there is no map legend today
To get this result I got support from two forum users "TrulloFetzer" and "Zossebart", who tested it al lot and gave me a lot of hints.
Some impressions of it.
