I wrote a little Chrome extension for this site (and MrExcel), it's rough around the edges, but if anyone's interested, I'll finish it off and stick it on the Chrome store for download or on here.

Currently it does the following:

Syntax highlighting for code tags (Alt + A)
Sub test()

    Dim cn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim sql As String

    Set cn = New ADODB.Connection
    cn.ConnectionString = _
        "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\MYFILEPATH;Extended Properties='text;HDR=Yes';"
    cn.Open

    sql = "Select * FROM " & "[MYFILE.CSV]"
    
    Set rs = cn.Execute(sql)

End Sub
Becomes:
Sub test()

    Dim cn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim sql As String

    Set cn = New ADODB.Connection
    cn.ConnectionString = _
        "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\MYFILEPATH;Extended Properties='text;HDR=Yes';"
    cn.Open

    sql = "Select * FROM " & "[MYFILE.CSV]"
    
    Set rs = cn.Execute(sql)

End Sub
Adds Profile info to posts to show when the user last logged in etc:



Adds Search options to the context menu:

(Search both threads is a bit sketchy, but it attempts to show threads where I've posted in the same thread as the user)

Adds a Google search bar for the forum:

Adds a quick preview (the full first post of the thread) to the search results:
