how do I change the font color? Kinda confused on that.

whats the simplest way to make the slidetounlock widget centered at bottom of screen and only 250px wide?

What did you change (it seems you have bad UnlockXL, UnlockXP values)?

#Some notes on settings:
# -Fonts: to set a font use a string composed with:
# "fontName;fontSize;fontWeight;italic"
# If fontName is empty it will be used the default system font.
# For italic use 1 to enable it.
# For fontWeight use one of the following values: light, normal, demibold, bold, black
# Example:
# Font=";14;normal;0"
#
# -Colors: to specify a color use R;G;B;A notation.
# Example:
# Color="255;255;255;255"
#
# -Position: you can set different position for portrait and landscape.
# PosL is the position in landscape
# PosP is the position in portrait
# For position you can use the special value: left, center, right, top, bottom
#
# -Size: : you can set different size for portrait and landscape.
# SizeL is the size in landscape
# SizeP is the size in portrait
#
# -Alignment: use one of the following values: center, left, right, top, bottom
