Set the Editor> Edtior Tabs
1) The Hide file extension in edtior tabs can remove the. php suffix and display more vertices.
2) You can set the Tab limit so that it will not be folded.

Right-click the tag, click "Table Placement", and select "right" or "left" to display the complete file name.

Right-click the label and choose "Table Placement"> show tabs in single row.
