[Feature Request] Some small QoL for image export

JFM

Hey there, there are some small issues while using image export that becomes annoying pretty quickly.

Firstly, when you choose single animation/skin it can't create folder automatically. So if I choose Desktop/Export, it just create images on Desktop instead of creating an Export folder. Thats not an issue if you choose "All".

Secondly, lack of subfolders when you try to use "All". It becomes quite chaotic when you export 5+ animations with 5+ skins. It would be awesome if it can automatically organize by creating subfolders for them. Like

Anim1
--- Skin1
--- Skin2
Anim2
--- Skin1
--- Skin2

Because of these 2 issues that kinda complement each other, I am currently doing it manually and its quite annoying :') I think adding a tickbox here wouldn't make UI too crowded as well

Take note of the label before the output path:

When the label says Output folder it will create the folder if doesn't exist. Desktop/export will create an export folder if it doesn't exist and put the files in it.
When the label says Output prefix the trailing part of the path is not a folder, it's a name. Desktop/export will write on the desktop files export_00, export_01, etc. Desktop/export/name will create an export folder if it doesn't exist and put the files in it name_00, name_01, etc. There is an exception to this, if Desktop/export/name already exists as a folder, then Spine will put the files inside that folder.

If doing a lot of exports, you may want to write a CLI script. Claude or ChatGPT is good at helping with this. It can turn hundreds of clicks into just running a script, especially when you have to do it again in the future.

It's true when exporting many animations/skins that it can be a lot of files. One solution could be to create a script that automatically moves files into folders based on their names. You'd export as normal, then run the script and it'd move each skeleton-skin-animation*.png into skeleton/skin/animation*.png. That's nice because you can customize the structure and it could work on any exports.

A Subfolders checkbox is an interesting idea and easier than making a script, which some animators aren't interested in. One issue is that the output structure is somewhat arbitrary. You want animation/skin folders while others may want skin/animation, skin/skeleton/animation or something else. A more powerful way to do it without resorting to a script is to allow placeholders in the path, like $skeleton/$skin/$animation-$frame. This would also allow using eg -00 instead of _00. We have an issue for that enhancement here:

I didn't realize there was "output folder" and there was "output prefix". Imo its kinda confusing for no reason but I guess there is a reason?

And I thought about making a CLI script but I was kinda lazy about it haha, might give AI a shot since it should be easy enough to handle.

About the subfolder suggestion, actually that checkbox + variable-naming support would be the perfect solution as you could basically create the whole folder structure with naming alone. If you don't use checkbox you would have one full folder of images with your prefered naming scheme like

AA-1.png, AA-2.png, BB-1.png, BB-2.png

but if you do use the checkbox it would be
-AA
---1.png
---2.png
-BB
---1.png
---2.png

Sounds like best of both world.
