In concept - I wanted to do as much as I could of this suggestion using only capabilities which are currently available in PSu. Here's how I'm approaching it.
Rather than "placeholders" I want to set "Version Usage Tags" ("VUT"s) which define which Managed Versions are intended for which purposes.
VUTs need to be specific to files, and not shared across Version Sets. I can only see one way to do this with current PSu capabilities: Custom Input Fields. There is one field defined for each VUT. The idea is that I put a value of "Y" in the field if that VUT is assigned to that file.
At present my VUTs are defined in the following Custom Input Fields:
- xmp.icd.QV2Main --> Main (In principle this might not agree with PSu's designation of Main, but I think it's probably easier if it does agree.)
- xmp.icd.QV2Display --> Display version (ie preferred Version to display when I don't want the whole set shown separately; there might be more than one if the same original leads to more than one good interpretation. I'm still thinking about this.)
- xmp.icd.QV2Camera --> Camera (ie original with no destructive edits; applies equally to Raw or Camera jpg)
- xmp.icd.QV2BW --> B&W
- xmp.icd.QV2HDR --> HDR (one of an exposure bracketing set intended for HDR rendering)
- xmp.icd.QV2XNoVUT --> No other VUTs assigned (This is a housekeeping item which I'm not using at the moment)
I use a custom thumbs script to see which files have which VUTs attached. In the thumbnail custom info line, working from left to right:
1. The number shows how many versions there are in total (including Main). The number is shown in blue if it's 1, otherwise it's white.
2. The triangle is blue for unversioned, Green for PSu's designated Main, Red for other Managed Versions.
(This means that if my designation of "Main VUT" agrees with PSu's system designation of Main Version, then the triangle and the following M are the same colour.)
3. Then the VUTs are indicated by their initial letters. If the value "Y" is set in the corresponding custom input field, this letter will be shown in green. If the value "N" is set, the letter is shown in red. Otherwise, it's in blue.
(M for Main VUT, D for Display, etc)
4. Then the star ratings indicator - I'm trying to find something compact and easy to recognise at a glance. 1 quadrant = 1 star, 2 quadrants = 2 stars, etc, and if it's 5 star then fill in the whole square. The example has 6 images rated in descending order from 5 to 0. (I have turned on the tweak that keeps ratings synchronised across a Version Set.)
I'm still trying to figure out whether this really works and is worth the effort. I think so, but there are still some complications to sort out.
