Here are some grammar corrections for the English version of the preferences pane (from a native speaker)

In the Preferences window:
* Main setups -> "Main settings"
* Extra setups -> "Extra settings"
(setup has no plural form)

* "Set sticked" -> "Set sticky" (or "Show on all desktops")

* "Set on top" -> "Keep on top" (or "Always on top")

* "Select always today":"Select always today" -> "When calendar window is opened":"Select Today's Date"
OR
as a radio box: "On Calendar Window Open": 1. "Select Today's Date" or 2. "Use Previously Selected Date"
