Programatically Loading Themes

[MerlinUKRhapsody]

I'm using the recommended approach of using .properties files
I'd like to provide my users with the option of defining their own themes by providing the same files which my app would load at runtime. Is that possible ? I couldn't figure out a way of dynamically loading those files at runtime.

Yea had a similar idea.

Currently a change in the properties file requires a restart of the application to be applied. It would be great if we could simply reload the properties + a refresh like during a L&F change (light to dark) to see the changes.

It would improve the design process for colors and other properties.

And as @MerlinUKRhapsody says also would allow this for the user. I also can think of a settings panel where some parameters can be changed by the user and will be applied to the properties file or a layer in between.
