@badnames was there already something done by you in this direction? Does the backend implement pagination?

[markus2330]

@badnames is there something still missing here?

[badnames]

Pagination would be supported in the backend, but it is not used by the frontend.

@badnames Please say which files you do screenshots from, otherwise it is an unnecessary difficulty for anyone working on this. Probably even better would be the feature from GitHub to link code.

Are there several places where the pagination would be needed or is it only the one search in the plants layer?
