For instance, here is a tooltip customization for movies group file type. It works great with media info.
{infotip}
<#B0B0B0>――――――――――――――</#>
Type: {type}
<#808080>Création: {created}</#>
Modification: {modified}
<#808080>Attributs: {attr}</#>
Taille: {sizeauto}
Save it. Check if it works when hovering a video file.
Go to DOpus settings and change language. All tooltip customization are gone.
I’m so glad I made a backup and could restore customizations I made along years.
I wonder if other settings get lost during the changing language process.
