Changes so far:

QuickFolders Options conversion project

<label  />
==> 
<label  for="idOfElement"> </label>

<button />  
==>
<button>

30/11/2021
Completed conversion for remaining parts of options.html -
buttons and checkbox labels, i18n, de-chrome (most) icon paths

Pattern:

 <checkbox /> <label value="__myText__"/>
 ==> 
 <label> <input type="checkbox" >__myText__</label>

Next Steps: reference conversion, replace native icons.

Can icons from Thunderbird still be accessed by a html page? or do we need to supply copied versions...

roll out all data-pref- changes to all elements.

support or convert !!!

Radiogroups wired up!

<fieldset orient="horizontal">  - changed to class=hbox.
<separator> to <span class="separator">

Support for collapsed attribute:

*[collapsed=true] {
  display: none !important;
}

Added a class for buttons with icons and tabs in order to add icons (behave like list icons):

button[isTab], button.iconButton {
  display: list-item;
  list-style-position: inside;
}

Added test config option to suppress xul options dialog (general debug mode must also be enabled):
extensions.quickfolders.debug.suppressXULoptions

support for sliding alert (accessibility for blind people)

TO DO:

[ ] Version number - open version history

initBling( ) function.

reuse existing options window, is this possible?
wire up color pickers: at the moment there are no bound prefs - use a background notification for this?
convert palette dropdowns to <option> elements
white fill color for selected tab.
-moz-image-region = seems to be without alternative. (see paste button for license)
