Dear All,
This is my first proposal & code submit.
I will be very gratefull for you comments & feedback what can be done better.
Recently I often use 'column view' feature.
To my suprise in 'column view' user can't move rows up & down.
So I wrote a little code snippet to be able to do it, and I'm sharing it with
you.
Questions:
1. Why user can't move rows up & down in 'column view'?
2. Is this was intentional design decision?
I think 'column view' is missing one the core feel & functionality of org-mode
- moving rows (headings) up & down.
In my experiance with 'column view' & tables I shuffle a lot of columns & rows
order.
In my point of view 'core fuctionalities of org-mode' are:
1. moving 'things' headings, rows, columns
1. horizontally (left-right)
2. vertically (up-down)
2. cyclic visibility
Let's compare this functionality in 3 areas:
| | heading | table | column view |
|-------------------+---------+-------+-------------|
| moving left-right | [X] | [X] | [X] |
| moving up-down | [X] | [X] | [ ] |
| cyclic visibility | [X] | NA | [X] |
Cyclic visibility does not apply to 'table' because it operate on simple data,
which is not structured, nested.
'Column view' transform 'headings' into rows, and their properties into
columns, creating a table.
'Column view' is a combination of 'table' & 'heading':
'Heading' gives a 'table' properties for columns and cyclic visibilty feature,
because it provide nested structure.
'Table' gives a 'heading' a 'column view' on heading properties.
'Column view' is similar to 'table'. They operate on same actions & keybindings.
| | column view | table |
|-----------------------------+------------------+------------------|
| move column left-right | [X] | [X] |
| move column left-right keys | meta left-right | meta left-right |
| move row up-down | [ ] | [X] |
| move row up-down keys | | meta up-down |
| add column | [X] | [X] |
| add column keys | shift-meta right | shift-meta right |
| remove column | [X] | [X] |
| remove column keys | shift-meta left | shift-meta left |
I thnik it would be beneficial to have consistance interface in 'column view'
and 'table'.
Based on that, I propose to add functionality to 'move row up/down' in 'column
view' and set keybinding the same as in table above -> meta up/down.
Patch is in the attachment.
What others think about it?

Sławomir Grochowski
