I sent a PM to Ash about the feasibility of an official tile map plugin, but he never replied, and I think it was probably a bad idea to PM him about that anyway.
This is what I wrote in the PM:
hough such requests have been raised multiple times, I haven't really seen you comment on it, so I might as well chat with you about it directly, if it's not too much trouble.
Tile maps are common in 2D games for fairly obvious reasons. In C2, as you've previously established, Tiled Backgrounds are more suited in most cases for level design as they're optimized to be spread out and used in large numbers. However, the problem with this, is that Tiled Backgrounds most likely won't use fine collisions like sprites will, and they can't be animated. Right now, the way it works now is perfectly fine for games with level layouts like Braid.
And hell, a Sprite/Tiled Background mix for games with more traditional 'tile' layouts can be done, since there's now a snap-to-grid, but... A common complaint is that making levels from the 'tiles' is time-consuming, even with snap-to-grid and copy-paste. Tiled Backgrounds are also highly unsuitable for non-square tiles, such as isometric tiles.
Which is why people have been asking for tile-maps, and being able to 'paint' them. Tile Maps can possibly have the same advantages as Tiled Backgrounds, with the added bonuses of being able to change the Tile-Map at runtime (destroying tiles, or replacing them with others, or adding new tiles), giving tiles certain behaviors (like Solid and Platform), assigning tiles to families for additional functionality, and perhaps having animations and fine collisions (among other things that don't come to mind, right now). It would also improve the workflow of level designers going for a tile-map style of level design. It's obviously not a replacement for Tiled Backgrounds (since Tiled Backgrounds on their own are more suitable for certain other things), however.
Now, the question is, if and when do you see a Tile Map plugin being implemented in C2?
I really, honestly think a tile map plugin would do wonders for Construct 2.
