By brothel do you mean 'service'? You just have to uncheck the 'rest' box, then they will work in service if not set to another job.
For farm, the UI could be better. You have to click the open slot, click a character, select the resource, then click the slot again. I don't know why it doesn't update without that second click. You can also farm multiple resources at the same time from high growth characters, also not very obvious.
As for the "eft" (you mean Elf?) and "beast" thing, I don't know what you mean. Either I'm not that far in the game or you may be talking about Strive 1? Or by 'recall' you mean that one click button? The cities you need to manually travel to and from, same way as your mansion.
