To do what you want, you'll *need* to use variable="..." in the $list
widget.
This will allow you to keep the "parent" tiddler context as the
currentTiddler.
Of course, you have references *inside* the $list loop that you would like
to keep simple by having the $list use currentTiddler, but that would defeat
what you want to do with the "priority" field.
One way to achieve a mix of both, is to explicitly use the tiddler="..."
widget
parameter or wrap content in a $tiddler widget to set the inner context.
Something like this:
<$list filter="[tag[Task]!tag[Done]]" variable="item">
<$reveal type="match" state="!!edit_priorities" text="1">
<$edit-text tiddler=<<item>> field="priority" size="3" />
</$reveal>
<$tiddler tiddler=<<item>>>
<nobr> <$checkbox tag="Done" /> <$link /></nobr><br/>
</$tiddler>
</$list>
notes:
* the $edit-text uses an explicit tiddler=<<item>> param to point at the
individual task tiddler
* the $checkbox and $link are surrounded by a $tiddler widget that sets the
<<currentTiddler>> to the <<item>> value
* I've used the "short form" of <$link />, since you are just linking to
the <<currentTiddler>>
