Capture Previous Screen Region

Use Case

Many users repeatedly capture the same area of the screen—for example:

• Monitoring logs or terminal output
• Capturing application windows during development
• Recording UI changes during testing
• Taking periodic screenshots for documentation

Currently, the region must be selected manually for every capture, even if it is identical to the previous one.

Proposed Solution

Add a new command (and optionally a configurable keyboard shortcut) named "Capture Previous Region" that:

• Remembers the last successfully captured region.
• Reuses that region for subsequent captures without displaying the selection UI.
• Updates the stored region whenever the user performs a new manual region selection.

Optionally, the application could briefly display the remembered selection outline before capturing to provide visual confirmation for Mac and Win.

No implementation files or tests are named. Start by locating the existing manual region-selection flow and command or shortcut registration, then trace how a successful region is stored and reused. Done means a new Capture Previous Region command reuses the last selected region, updates it after manual selection, and avoids the selection UI.
