Thunderbird - Tasks: Grouping tasks by category

[Herzi-Linners]

I'm using tasks (ToDo's) quite a lot for different purposes and reminders. To have a better view, I use categories (with colours) for different task areas.

Some examples for categories:
personal, shopping, holiday, authorities, finance, healthiness, contracts and so on...

Has Thunderbird Tasks the possibility to group tasks by category?

As result, the view of all of the task's could look like this:
a) grouped by category
b) sorted by priority(first)
c) sorted by date (second) {this could be beginning or finishing date}

Category "Holiday"
- Task 1
- Task 2

Category "Personal"
- Task 4
- Task 5

The "Grouping by" view helps to navigate more comfortable in large lists. As additional feature it would be helpful to collapse or expand a category and the tasks beneath.

Annotation:
I moved from Windows/Outlook to Linux/Thunderbird: I found the usability from Outlook very helpful to manage data (emails, tasks, contacts, personalized views).

I have just spent the last couple of days with ChatGPT trying to get my tasks to coulur code using the Calendar Category colours without success.  I will raise a help case with Bugzilla shortly but does anyone have any information that will assist with this issue.  It appears that Thunderbird 159 (Native and Flatpak) both use a security layer that prevents the tasks from being manipulated with style sheets of embedded code.  I can provide the fault imformation if it is requested.
