I have a issue with the menu underline animated slider, it goes from thick to thin while moving over menu with mouse. If you try to move the mousepointer over the header menu so you see what i mean.

Hope there is possible to make this as a thin or thicker underline, not both thick and thin. :slightly_smiling_face:
