less (one :-) ) keystrokes to expand/collapse stacks

[akirot]

Working mainly with a graphic tablet I like the Lightroom approach to expand and collapse stacks: one click on one of the stacked images and the job is done. (Pen only is sufficient.) In Imatch Ctrl+Click on the top left icon on the topmost image does the job. If one wants to collapse the stack from a lower image it needs two keystrokes: one on the lower right icon to open the context menu, the second to collapse.
Please could you add at least the crtl-click on the lower right icon of a lower stacked image to collapse? Thus one does not need to return to the uppermost image to collapse or one needs two strokes.
I would prefer a click only solution for collapsing and expanding but I assume this cannot be implemented due to ergonomic design and consistency reasons.
I also like the Lightroom feature showing "x of n" when hovering over a photo of an expanded stack. If you have a lot of similar image sequences this helps identifying a specific sequence a lot. Couldn't this be implemented in Imatch as well?

Thank you for considering.

IMatch 5 is currently not optimized for touch-only or pen-only devices.  Adobe took several years and five paid upgrades to add deep support for touch/pen-only devices, so I expect it will also take some time for IMatch 5.

On the keyboard, you can always collapse a stack with <Shift>+<C> or <Ctrl>+<Cursor right>, whether you are on the top image or a stack element. You can left-click the stack icon and choose collapse, that should work with a stick as well as with touch-only. Works on the top as well as stacked files.

Or you use the stack panel to always see the files in your stack (LR has nothing similar as far as I know).

Or you use the stack tooltip to see all files without expanding the stack.

The "x of n" means what? The nth image in the stack of X files? In which sort order?
Is not the stack panel a much more useful approach? Or the stack tooltip on the top file, which shows the first 12 images in the stack just by hovering over it?

The mentioned Imatch features work very well as soon as the stacks are organised and ready.
Imagine having hundreds of newly imported images - a mixture of bracketing sequences and single shots of almost the same object. Due to the source of the images autostacking cannot be used - you stack manually. Later you realize having made a mistake you have to reorganise some of the stacks. As on a real lighttable with slides you expand and collapse.
From an ergonomic design point of view it would be best being able to use the same keystrokes on all members of a stack to expand and collapse.
Ctrl+click currently only works on the topmost stackmember - the idea is to have the same function on the other stack members too.
This request doesn't "need" a touch-only or pen-only environment - it fully applies to keyboard + mouse only.
Background: Avoid unnecessary (mouse) moves due to medical reasons ("Mausarm", repetitive strain injury).  BTW replacing the mouse by a pen is a good cure.
This is  not to insist on the feature request but just to give the background.
The assumption has been adding the ctrl-click is a no-brainer :-)

You can always use <Ctrl>+<Cursor left> and <Ctrl>+<Cursor right> to expand/collapse. Works whether a top or a stack member is selected.

You have to take your hand off the mouse or the pen from the tablet for this combination (if you are a right hander), this move can be avoided :-)

But for medical reasons it is quite a good thing to take the hand off the mouse or pen and do some other movements (hitting keys). 

Sorry, I could not resist.

Left-click the stack icon and choose collapse. Works without the keyboard.
