List of missing/outdated documentation pages

[OverloadedOrama]

This is a list of documentation pages that are either missing or outdated:

• 3D layers
• Importing (how to import images, palettes, as well as import options such as new project, frame, layer, spritesheet, reference image)
• UI customization (how layouts work, how panels can be moved)
• Image effects and how they can be animated
• How to change shortcuts
• Blend modes
• Mention z-index in the cel page
• Mention the palette file extension change
• Layer effects (non-destructive image effects)
• Change project structure now that they are .zip files
• Update the UI image on the user interface basics page.
• CLI
• Reference images
• Dynamics (pen pressure, mouse/pen velocity)

[Variable-ind]

• Crop tool needs mentioning
• Global tool options aren't listed in the interface basics (image also needs update)
• Paste tag system.

info about pixel, group, 3d cels can be added to the cel.md located in concepts,
layer and frame should also be added to concepts as frames_layers.md (frame is a collection of cels, i don't know how to define layers but we need to list different types of layers too)
