Make an app with a feature for the post composer that's a "hashtag drawer" that lets you individually save hashtags WITH CamelCase for easy re-use.
In the same app, add a feature to create timelines with "hashtag groups" similar to Sharkey's native "antenna" feature.
Icecubes has hashtag groups but it's limited to 4 hashtags which is fine. But the "recent hashtag" feature doesn't seem to save CamelCase.
Moshidon/Megalodon has the antenna timeline feature built into the UI of their app, but it only works for Misskey/Sharkey instances. I'm sure it can be worked into the app somehow to work for Mastodon. PLEASE.
Does @ivory have automatic timeline refresh? Asking for a friend...😝every time I download it, it hijacks mastodon links like it owns them. I use several Mastodon apps and I don't like this behavior so I tend to uninstall when I get annoyed with it.
