Description:
Actualmente, en LibreOffice Calc, el puntero de ajuste que aparece al posicionarse entre columnas o filas para redimensionarlas es una línea muy delgada, lo que dificulta su visualización, especialmente en pantallas con alta resolución, condiciones de poca luz, o para usuarios con problemas de visión.

Sugerencia de mejora:

Añadir una opción en las preferencias de usuario que permita personalizar el grosor, color o estilo del puntero de ajuste (por ejemplo, hacerla más gruesa o darle mayor contraste).

Alternativamente, adaptar el grosor automáticamente según el nivel de zoom o resolución de pantalla.

Esta mejora contribuiría a una mejor experiencia de usuario, reducción del cansancio visual y mayor productividad al facilitar tareas repetitivas de ajuste de celdas.

Justificación:
Esta característica es común en otros programas o sistemas que cuidan la accesibilidad visual. Incorporarla en LibreOffice sería coherente con su misión de ser una suite ofimática accesible y potente.



Actual Results:
When hovering the mouse pointer between columns or rows in LibreOffice Calc to resize them, a very thin vertical or horizontal line appears. This line is hard to see, especially on high-resolution displays, dark backgrounds, or for users with visual impairments. There is no available setting to increase its thickness, contrast, or visibility.

Expected Results:
This is not a bug but an enhancement request. However, here is how to observe the issue:

Open LibreOffice Calc.

Move your mouse pointer to the border between two column headers (e.g., between column A and B).

Notice that the resize pointer appears as a very thin line, which is difficult to see on high-resolution screens or for users with visual impairments. There is no setting to increase its thickness or contrast.

Expected behavior:
An option in the settings to increase the thickness or visibility of the resize pointer to improve accessibility and usability.


Reproducible: Always


User Profile Reset: No

Additional Info:
This enhancement would benefit users working with high-resolution monitors, users with reduced vision, or those who spend long hours using spreadsheets. Increasing the visibility of the resize pointer would reduce eye strain and improve overall usability. Other office suites offer better visibility or customization options for such interface elements, and adding this feature would align LibreOffice with modern accessibility standards.
