Vector maps, layers, themes

Hello,
I am new to outdoor navigation using an andriod mobile phone...
I am testing Oruxmaps since one week and I am very impressed.

I don't know if it is possible, but I'd like to have "switchable Layers" like contour lines, shades, hiking paths, bicycleways, POIs... (like drop down menu in google maps). It would be also very nice to "customize" vector maps by highlighting wanted details (color, line type etc.) or hide some unwanted details.
(sorry for my bad english...)

BTW, in the german translation for Oruxmaps are some bugs. Is there a translation table where I could correct the mistakes?

For me this runs a direction like Locus ones, changable themes or render styles.
Oruxmap's support of offline maps is perfect... "offline mape here", so why no "alter render theme"?
It would be a great advantage for developing and testing styles.
