[TASK] Adapt arrangement of sites config for better read- and usability

[helsner]

Currently the 4 read fields are all aligned within the same row which is ok, but also not pretty spacious. When you use another host than localhost the usability suffers as one cannot read the full host without scrolling horizontally within the field. My proposal would be to rearrange that and simply make it 2x2 row + column with a bigger field for especially the host.
