Can we document some important requested features in the docs and their status?

[RayBB]

For example:

Auto saving articles from an RSS feed - https://github.com/wallabag/wallabag/issues/3360#issuecomment-334986272

• Because wallabag is for saving content you've already screened

Email to wallabag - https://github.com/wallabag/wallabag/issues/239

• Not yet supported but can use third party tools like https://git.sr.ht/~harmtemolder/wallamail
