Corebird is a Twitter client for Linux. It has a UI that I find to be clean and modern.
$ sudo apt install corebird
Adding a Twitter account is easy and multiple accounts are supported.
Configuration can be done by clicking the ⚙ icon at the top-right. These settings are very minimal though. For example, I could not find an option to set the number of tweets to show is not provided.
Tried with: Corebird 1.1 and Ubuntu 16.04
