Thanks a lot, it's getting better an better.
- Change of order of the menues: Bibliothek | Regale | Sonstiges (more logical; "Regale" is shorter than "Bücherregale")
- "Sonstiges"-menue: "Library" is redundant, remove it. Translation for German: Browser = Internet; Reboot = Neustart; Reserved = Frei; WiFi = WLAN
- Toggling WiFi function: On/Off
- 1.9.17 style favorite books at the bottom of the start page
- A Tweaks Plugin style Window to choose options including those for "Sonstiges"
