Optional global border around screenshots

[suprunchuk]

Feature Description

Add an option to automatically apply a thin border around the entire screenshot.

Proposed behavior:

• A configurable checkbox in settings: “Add border to screenshot”

• Border applied after capture, before saving/copying.

• Configurable parameters:

  • Border width (e.g. default: 2 px)

  • Border color:

    • Solid white

    • Fully transparent

    • Custom color (optional extension)

• Border applies to:

  • Region captures

  • Active window captures

  • Active monitor / full screen captures

Why this matters:

• Borders improve visual separation when screenshots are placed on white or dark backgrounds (documentation, messengers, issue trackers).

• A 1–2 px border is a common requirement for technical documentation.

• Avoids post-processing in external editors for a trivial operation.

• Windows 11 “Snipping Tool” already provides this as a one-click option, proving the practicality of the feature.

This should be a simple, optional, non-intrusive enhancement that improves output quality and reduces manual editing steps.
