i want to do several minor changes about layout...

HI there

i need to do several minor changes on easydiscuss.

1, how to move category label and how to decrease height ? ( just like attached pic, reference is T3 Framework website discuss page , i want the same)

2, how to remove search bar from "ask question page" , "profile page", "edit profile page", "conversation page", " notification page" ?

3, can i change color of "post type" ?

PS. my sites is on localhost, so i can't give you backend.

thanks
