When I edit the calendar, I would like to not see all the values in the specification copied into the URL, just those that differ.

Example:

https://open-web-calendar.hosted.quelltext.eu/calendar.html?clean_html_annoying_tags=true&clean_html_comments=true&clean_html_embedded=true&clean_html_forms=true&clean_html_frames=true&clean_html_inline_style=true&clean_html_javascript=true&clean_html_links=true&clean_html_meta=true&clean_html_page_structure=true&clean_html_processing_instructions=true&clean_html_remove_tags=body&clean_html_remove_tags=head&clean_html_remove_tags=html&clean_html_remove_unknown_tags=true&clean_html_safe_attrs=src&clean_html_safe_attrs=color&clean_html_safe_attrs=href&clean_html_safe_attrs=title&clean_html_safe_attrs=class&clean_html_safe_attrs=name&clean_html_safe_attrs=id&clean_html_safe_attrs_only=true&clean_html_scripts=true&clean_html_style=true&compact_layout_width=600&contributing=https%3A%2F%2Fopen-web-calendar.quelltext.eu%2Fcontributing%2F&controls=next&controls=previous&controls=today&controls=date&css=&css_url=&date=&description=&ending_hour=24&favicon=%2Fstatic%2Fimg%2Flogo%2Fowc.svg&hour_division=1&hour_format=%25H%3A%25i&javascript=&javascript_url=&language=en&loader=%2Fimg%2Floaders%2Fcircular-loader.gif&privacy_policy=https%3A%2F%2Fopen-web-calendar.quelltext.eu%2Fhost%2Fprivacy-policy%2F&skin=dhtmlxscheduler_contrast_black.css&source_code=https%3A%2F%2Fgithub.com%2Fniccokunzmann%2Fopen-web-calendar%2F&start_of_week=mo&starting_hour=0&style-event-status-cancelled=false&style-event-status-confirmed=false&style-event-status-tentative=false&tab=month&tabs=month&tabs=week&tabs=day&target=_top&template=dhtmlx.html&timeshift=0&timezone=Asia%2FCalcutta&title=Open%20Web%20Calendar&translate=https%3A%2F%2Fhosted.weblate.org%2Fengage%2Fopen-web-calendar%2F&url=https%3A%2F%2Fcantonbecker.com%2Fastronomy-calendar%2Fastrocal.ics
