GIMP-scripts dedicated for editing tiles or similar

[NeonSturm]

1. It would be nice to have GIMP (or similar OS, Linux program) which shows the very same texture in different resolutions next to each other and auto-updates them when you edit the high-res.

• GIMP only shows these in multiple layers and requires manual clicking.

2. Also I miss a tool which adjusts the pixel+grid size you are currently editing:

|\ /|\ /| v s X X
|/ \|/ \| . . X X
|\ /|\ /|
|/ \|/ \|
Selection of the quarter of a block you want to edit (top,left,right,bot) and size.

This means instead of a

5x5 pixel shape that hops from xy 4,4 to 3,5,​

you would have

1x1 | 2x2 | 4x4 (selectable) that hops from xy 4,4 to 3,5 | 2,6 | 0,8 (position modulo size)

​

3. If I want layers like:

1. computer-circuit on the bottom layer,
2. a casing with some holes on the middle layer,
3. casing deco (individual per block)
4. overlay (dirt, etc) that only applies where 2 is not opaque.
5. overlay layer.

GIMP does not support me with 4 and does not let me cycle through possible L2-layers + possible L1-layers compatible with each other.

Neither can I see previews with+without 4+5 next to each other (requires 2 clicks at very small buttons in a maybe-long list of layers)

​

Because of this we need GIMP-scripts or a whole new editor dedicated for editing tiles.

But perhaps there is already something I don't know of.
