Thank you for carrying this over. I've added a few suggestions about »naming things«.

Edited, thank you for good suggestions.

Thank you, approving. Currently, it does not make sense to employ the redirects, because GH-53 will change the structure: Both "document" and "search" will go to the "Features" section, so redirects would need to be changed for another time.

I think I wanted to make you aware of this, so you could have derived your feature branch directly from amo/timeseries-more. Apologies if I missed that, so please go ahead and just merge, in order to let me do the refactoring afterwards.

Ah, I forgot about that one.
Your #53 was started before this, please go ahead. Happy to wait and shuffle this around when it fits
