I've been using Phanpy (https://phanpy.social/) as my #Mastodon client of choice on mobile and occasionally on the desktop for about a year. The Boosts Carousel is too cool, and the threaded posts just add to the experience.

This evening, I was digging into the settings a bit more and whoa, next level! I always loved the Mastodon "advanced web interface" because it was like Tweetdeck of old. Phanpy lets you create columns like that on your desktop. Or, for your smaller screen devices, you can set up easy menus at the top of the screen or floating that let you easily switch between the items. For example, I have shortcuts/columns for my home feed, a list or 2 I have created, a couple hashtags I like to keep up with and one for my notifications.

Give Phanpy a try!
