Editor Feature Suggestion: Layer system for the editor.

[roltemurto]

When there are multiple objects, terrain etc on top of each other, with similar sizes and irregular shapes, it becomes impossible to select the desired asset.

For example on the design I am currently working on; I have a terrain piece on top of a very large piece of steel and an exit object on top of all.
I had to move the terrain back in order to align and position my exit but now I am stuck with not being able to select it because of the steel which blocking the way.

For my particular problem; an option to Show/Hide Steel (like any other layer) would solve it immediately.
Steel is the only asset type that hasn't got an option to hide/show.
I know steel is also technically a terrain, but I am referring to the distinction between steel and not steel.
Because in my example, I need to select the "not steel" terrain which is below the steel.
I fear it may not be possible to implement since the editor sees them all as terrain
but am hoping using it's flag etc would allow it.


An option in the settings or a modifier key press; that simply allow bypassing the alpha channel when selecting, would also save me right now.
I believe CTRL+Click and/or holding down the left mouse button 'sometimes' help with selecting an object which is behind of another,
but because of it's inconsistency I'm not so sure if this feature actually exists or not.

What would be a QoL update is; an actual toggle button to let the cursor prioritize and select the layer at the back/behind.

What would be an even better addition; is the layer system implementation;
Currently there is no way to tell how many layers are there or which and what layers are currently on the map.
This also makes it impossible to clean/delete an asset that has been removed/changed from the style folder,
because there is no way to select it once the editor is restarted, the level is reloaded or simply the styles has been refreshed.


If there was a file list or a layer system, that would allow;
- Eliminating the need to use the "depricated" feature. Since the assets can be selected and deleted from there,
- The ability to select/move, show/hide layers and objects individually,
- The ability to see/find assets at a glance, since it is outlined as it's selected,
- The ability to see/find how many and which assets are currently placed on a level,
  (assuming the filename is used for layer name instead of effect type)
- Make grouping and organizing much easier,
- Possibly allow to Show/Hide asset groups or groups of layers.


I hope I was able to explain the situation that I am struggling with.
Please let me know if I am missing something and if there's an already implemented way of working or selecting 'the object behind'.
Because even the marquee doesn't always help.
