Kobo dictionary and fullscreen questions

Hi,

The Kobo Aura One looks really interesting. I have a few general Kobo questions that I did not see answered, and I have not owned a Kobo device before.

1. Does the official reader for epubs on a Kobo device allow a translation of an English word into another language (German in my case) with a single fingerpress/fingerholding on the word?

2. Does the official reader for Kepubs (I read here that they are separate programs) allow the functionality above?

3. I read this thread here: http://www.mobileread.com/forums/sho...d.php?t=232883 about installing custom user-dictionaries on a Kobo. Is this still possible on recent firmwares as of now?

4. Is the problem from Firmware 3.18.0 fixed, where when setting FullScreenReading=true the “Show header and footer” option unticked, every next page was the extra-heavy full screen refresh?

5. Can the wifi option be fully disabled in a Kobo, including the search for open wifi signals? This can improve the battery lifetime, as I am oftentimes reading without a wifi connection around.

Thanks!
