[Feature request]: LED corner skip

[kopidoo]

Is your feature request related to a problem? Please describe

LEDs at the corners might be not present because of hardware connections.
The gap where there is no LED could vary based on the strip LED count and the connector/connection at the corners.
E.g. the L-shaped connector with a strip of 60LED/m (or higher) could have a significat impact.
The LED count remains and it shirnks the grabber area. The grabber isa not using the corners.
Gap:

No gap:

L-connector:

Describe the solution you'd like

The corners should have a horizontal and vertical adjustment feature for the gap.
The values should be on a precent scale.
The adjustment should be symmetric for left-right, and top-bottom.
