HTML in addition to plain text in description area (tips to use cloud-based doc to emulate this while waiting for better)

	Currently, only plain text is allowed in the description area which is 
because of iCalendar standard.

	Is there any plan to use X-ALT-DESC in order to have format rich text? 
Honestly, having formatted text (like in Outlook's calendar and task 
events) is very helpful.  I use calendars a lot to organize things / 
tasks.  I write a lot of things inside the descriptions, eg steps in a 
task and at which steps I'm currently in, etc.

	Having formatted text helps a lot because I could spot the main point 
in the whole description that I have written several weeks ago and that 
I can't remember clearly.  Without format, I have to go through quite a 
big part of the description to find back where I stopped.

	Of course, I could use my own markup language like /***/ but this 
method has its own limits.  Sometimes, I would like to make some texts 
red and some other blue, for example, to show the different degree of 
importance in the description.  Without format, this is tough.

	As Thunderbird's "Compose email" dialog is able to let users edit plain 
text as well as HTML text, if it's possible to reuse this component, 
that would be great.

	Anyway, while waiting for this uncertain implementation in the future, 
let me give a little hint to those like me:

* Create a document on some cloud-based file hosting service, eg Google 
drive / Google doc
* Copy the URL of the doc
* In Event dialog, click "Attachments:" tab
* Paste the URL there

	This method is of course not perfect.  And actually quite cumbersome. 
But that's the best I can think of at the moment.
