Few features of iTerm2

1. Split Panes

iTerm Split Terminal Vertically and Horizontally Example

Though macOS Terminal does allow to have multiple tabs within the Terminal Window, it does not let you split the panes to work more efficiently, this is one of the much-craved features that iTerm2 adds. You can divide a tab into multiple panes with each having a separate session.

The panes can be sliced both vertically and horizontally and there is no limit to the number of divisions you can have at a time.

2. Autocomplete

Just like IDE's you have autocomplete with iTerm2, as you start typing, the suggestions will appear, and press Command + ; to get the suggestions window.

3. Paste History

You can revisit recently copied or pasted text.

4. Search

iTerm2 has a find-on-page feature, as you search the matches are highlighted. You can even make use of regular expressions.

5. Multi-Lingual

There is internationalization support, including support for Unicode combining marks, full-width characters, Emoji, and many other Unicode features.
