[Feature Request] Option to close WinMerge when last tab is closed

[tildebox]

In WinMerge, when I close the last tab, the program stays open. In web browsers, when the last tab is closed, the program also closes.

There is a setting to close WinMerge with Esc when the last tab is active, but this is cumbersome when using only the mouse. I ask for a new option: when the last tab is closed, WinMerge should also close automatically.

This would make WinMerge faster and more comfortable to use.
