Improve sorting, add missing sorting, sort order for "no", show "no"

[aisbergde]

Feature Request

add missing sorting features are:

• completed (yes / no)
• threshold date in future (yes / no)
• alphabetical
• File order (unsorted)

no item:

• when sorting, the "no" should be in the right place (no context, no list, no priority, ...): meaning, alphabetically at the beginning, when sorting is ascendant order (no = '_'). Currently it is at the end. destroying my workflow.
• Make this an option, because other users maybe like it, as it is
• best would be to allow to set this per sorting category. For example, I want to see the "no context" in front of other categories, but I want to sort the "no priority" behind all other priorities (as it is now)

the "no" item marker should also be seen in the list. Currently, it is just at the end of the list, and it is hard to distinguish between a category and no category:

What problem does it solve?

I want to be able to sort my tasks in sleek in the same order, as I can do on my mobile client (SimpleTask)

How does the user interface change to accommodate this request?

Get creative; Provide a detailed description of how you envision incorporating this feature into sleek.

I've mentioned some of this also in #368 (comment) e.g. " "Threshold date in future" and "Alphabetical" order.

One more idea regarding sorting order would be "Forecast" which is sorting by date with a twist:

• for non-recurring tasks and recurring without t: - take creation date
• for recurring tasks with t: - take t:
• for completed tasks - take completion date

As a result you should get a list of

• completed tasks ordered by done date
• pending tasks roughly in execution order
