Clear new bar with my own websites (editable)

Hello. I am looking for some tool to EDIT the NEW PANEL window.
I want to put there my own websites, probably make my own lines with descriptions, and have control about that - not like having 2-3 lines without possibility to EDIT it more.
Does it exist? please.

as I cannot open the site in english, I give it in google translator, or under that, there is URL in czech language and put it to google translator to see, as this forum is english. thanks
