In order to prevent KSM from being wiped off when you sign out from your Kobo account, the recent version is located in the folder
.adds (previous versions were located in
.kobo).
If you like you can also change the position of koreader and vlasovsoft (Kobo Launcher, including Cool Reader).
Koreader:
When installing Koreader, copy the folder
koreader into
.adds instead of
.kobo. If Koreader is already installed, move the folder
koreader from
.kobo to
.adds.
Kobo Launcher, Cool Reader:
Move the folder
vlasovsoft from
.kobo to
.adds.

If you want to be able to start the Kobo Launcher from within nickel via fmon (which I do not recommend), you would have to modify the script .kobo\fmon\launcher.sh to account for the new location of the vlasovsoft folder. (If you move the folder fmon, and the script on_start.sh too to .adds, you will have to modify also the scripts on_start.sh, and etc\init.d\on-animator.sh.)
