Improvements for Photoshop Sprite Export Process

[Aodaruma]

Is your feature request related to a problem? Please describe.
The current process for exporting sprites in Photoshop requires manually selecting all the necessary layers. It's quite time-consuming to individually select and export around 20, 30, or more layers. Additionally, if there are layers with the same name, importing them into Blender results in issues, causing identically named elements to disappear. Due to these bugs and inconveniences, there is a desire to create a script to address these problems.

Describe the solution you'd like
There are several proposed improvements, primarily focusing on the following objectives:

1. Enabling the simultaneous export of necessary layers without the need for individual selection.
2. Implementing a solution for handling same-named layers.

To achieve this, several enhancement methods are suggested:

1. Automatically select visible layers within Photoshop and export them all at once.
2. Revise the naming convention to reflect the group structure.

For example, if layers are organized under the structure "Character→Arms→Line→L," exporting them with names like "Character.Arms.Line.L.png" would eliminate the need to assign full names individually, reducing effort during renaming and enhancing convenience.

However, considering that layer grouping structures can vary greatly based on individual creators' preferences, the adoption of the second approach should be carefully considered. In some cases, offering it as an option might be more favorable.

I would like to see an option to add padding around layers - that will make the process of editing meshes easier

[Aodaruma]

I think a feature to add padding to layers is very nice. However, since the develop branch already allows mesh editing beyond the range of the image, I think it might become a duplicated feature of that

Turned out the padding (margin) is already implemented:

I have been working on this issue for a while now.

• Improved the UI and added properties
• Improved and refactored the algorithm
• Added some features
  I don't plan to make any more additions or modifications at this time.
