I didn't find zellij to be better than screen. The tabs/screens are not numbered correctly so switching directly to them requires manually counting. A non-starter for me.
If you don't like the default tab bar, you can use the zjstatus plugin (https://github.com/dj95/zjstatus) to replace it with a customizable one that can show the tab index.
From memory the index is different to the position, so if you rearrange our delete tabs the numbers become meaningless. I submitted a PR but the developers wanted it to be a separate plugin for just this. I decided it wasn't for me.
