Merge the Layers and Objects views #3382

I like "Outline", but "Layers and Objects" would probably be easier for newer users to find in the Views and Toolbars menu.

As I mentioned on Discord: For maps with many non-Object Layers, having a separate tab for objects makes it quicker and easier to get to the objects. it also avoids the need to collapse the Object Layers to ease navigating the other layers. So unless we also have some easily accessible filters by layer type on this panel, I'd rather keep them separate.

I would rather not have position shown for layers, it would be distracting, and not useful for me. Could it be made so that if offset is 0,0, it's not displayed at all? That would also make it easier to notice when you've accidentally offset a layer.

Overall, I think I'd rather see them not merged. For my workflow, it offers no benefit, but makes the panel more annoying to navigate and more visually cluttered.

As a counterpoint to Inkscape: Photoshop's Layers panel only shows layers, including vector layers, but has a separate tab for Paths, which are the editable objects. Much like Tiled's current behaviour, you can select any Path on the canvas no matter what layer you're currently on, and its layer will be selected, but if you want to select via a list, you go to the Paths tab. I think Photoshop, being a mixed raster and vector program, is a better art analogue to Tiled than Inkscape is, too. In Inkscape, you're always dealing with Objects, so it makes sense to merge the lists. In Photoshop and Tiled, that is not the case, and the separate Objects view lets you focus on just objects when you need to.

All additional columns (Type, ID and Position) can already be toggled on/off by context menu of the header. I should probably look into making that easier to discover.

There would be a persistent (stored in session) toggle whether objects are visible in this unified view or not. So switching between seeing objects or not should still be as easy as it is currently to switch between the Objects and Layers views.

But I do want position visible for objects. Just not for layers xP So I'd want them in the Objects panel, but not the Layers panel.

Unless Tiled saves separate settings for the panel based on whether you have objects enabled (in which case it's functionally just a separate panel anyway, but with more clutter than just a tab bar), I just don't see the benefit for my workflow, which tends to oscillate between doing a bunch of Object work and a bunch of non-Object work ):

Edit: To clarify, I'm not entirely against this change, I just hope that the new merged panel can be made as easy to use and uncluttered for my workflow as just switching between the Layers and Objects tabs xP

Many months later edit: I still feel the same way. I'd like to see the ability to nest objects and object groups within objects (which is a separate issue), but I do not want to see the layers and objects views completely unified, as I use them in different ways and find their separation quite convenient. Even if unified, I would want to continue to use them in separate ways.
