Found a workaround for this in Tusky.

Account preferences - Tabs - [+] Hashtags

Works for posts but seems to filter out answers. I'm 90% happy with this.

Meanwhile I got a new idea: Lists that contain hashtags and people. That would be the perfect solution.

#mastodonclients #tusky #mastodonlists

On my wish list for mastodon client apps:

Please show me in favored or boosted messages, if I already follow this person oder not.

Thicker border around Icon would suffice. Overlayed Arrows oder Double Arrows would be even better, showing following and being followed.
