Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

• The whole editor layout expands beyond the visible window/viewport width
• Horizontal overflow appears
• Parts of the interface on the right side become cut off or difficult to access

Expected Behavior

• The editor should remain constrained to the viewport/window width
• Opening many files should not cause the overall layout to expand horizontally
• Only the tab area should handle overflow, for example with horizontal scrolling, tab shrinking, or an overflow menu

Steps To Reproduce

1. Open CPEditor on macOS
2. Open many files so that the number of tabs exceeds the available window width
3. Observe the file tab bar at the top of the editor

CP Editor Version

7.0.2

OS

macOS 15.6 Sequoia
