Regarding the process, the code review should rather be done by @dr0i and I can do functional review if you deploy it to staging.

[TobiasNx]

@acka47 you were intended for the functional review:

it is on staging: http://quaoar13.hbz-nrw.de:7508/resources/990134555090206441 and http://quaoar13.hbz-nrw.de:7508/resources/990368617770206441

Was already included in the initial post, I messed up one of the links above, fixed it.

not sure if @dr0i or @fsteeg should review the webapp changes.

Damn, sorry for this. @dr0i deployed it on test on friday, maybe this was overwritten, or because of the small index is not included. Will get back to you, when this is fixed

Deployed on test now: http://quaoar13.hbz-nrw.de:7508/resources/990134555090206441 .
