Thank you! I have multiple tasks on my plate, so there might be a slight delay in my review.

No problem. As the next steps I had in mind to improve the way colors and other styling are organized to be able to change the theme by adjusting a few variables.

I hope this makes it possible (and easier) to collaborate on the fundamentals of a theme but still have the flexibility to customize.

@dkastl Since I'm not particularly adept at CSS or JavaScript, your contributions in these fields are invaluable to me.

I intend to use this theme for a short period to ensure that the changes in icons have not made it more difficult to understand. Please bear with me, as it may take a bit more time before we are ready to proceed with the merge.

@dkastl I have collected some feedback on the changes made by this pull request. Considering the feedback points, I think it might be better not to completely unify the icons to Solid style.

• It's better not to change the font size.
• Changing icon-fav-off (icon when not watched) to Solid could lead to misinterpretation as a 'watched' state due to it being filled in black. It's more appropriate to maintain its current Regular style.
• In the Gantt chart view and other areas, switching fa-sticky-note to a filled black icon makes it too prominent and darkens the screen's appearance.
• The current jstToolbar 'pre' and highlight icons should remain as they are. It is confusing to use the fa-code icons in a different context than before.

@dkastl I find it difficult to merge this pull request as described above. I regret that I am unable to merge your deliverables, may I close this pull request?

[dkastl]

OK, no problem. Thanks a lot for looking at it.

@dkastl Many thanks.
