Help me customize a few things on my XenForo

Hi guys,

I'm looking for somebody who could help me with a few smaller modifications on my site. Let me know your bid in PM if your interested.

- remove this transparent blue space on my search bar, I can't get it done
- as a guest, the sidebar should be active at all times (and not disappear once you start reading a thread, as a guest) -> same would go for users; the sidebar should be present at all times; I want this to be done without a widget/addon
- customize/design the footer based on an existing site (will give more details, isn't really complicated)
and a few such smaller edits.
