Multiline editing

It's not immediate like other editors but it's possible, the best option is to use a plugin like vim-multiple-cursors.

Append text

This works out of the box in vim: with Visual block mode select the lines you want to append text to, press $ to move the cursor at the end of line and then press A to start append mode. After you terminated to insert the text, ESC and wait the text to update.

Edit multiple files at once
