Mikutter is a Twitter client for Linux. It is developed using Ruby.
$ sudo apt install mikutter
When you start it for the first time, a bot-like mikutter-chan will lead you through the steps to link your Twitter account with the client. This is quite user-friendly.
It supports multiple Twitter accounts. Just click the 🔧 icon at bottom-right and go to Account information to add more accounts.
One feature I like in Mikutter is that it shows the original message below reply tweets.
I find the message list display to be quite crowded, though usable.
Tried with: Mikutter 3.3.6 and Ubuntu 16.04
