Tools for drawing tiles faster in 2D editor (filled rectangle, filled circle, line)

[clockworkprince]

I've been trying to make 2D games based on tiles and I've been a bit frustrated with having to place tiles one by one in the 2D editor. The selection tool helps a little bit, but it's a bit cumbersome to use, unfortunately. Please note that this isn't meant for changes within editing the tiles themselves, but placing the tiles in a 2D scene.

What I propose is to include some simple tools to make tile placement faster; basically the same way they work in MsPaint, except they'd place tiles instead of pixels. (This functionality is already present in engines like the RPG Maker series, if you want a game engine reference for what I mean in particular.)

Ranked based on how much I want them, from most to least wanted:

Filled Rectangle: Place tiles in a rectangular shape in the 2D editor. Reads the coordinates where the user starts to press the left mouse button and the coordinates where they release the left mouse button, then creates a filled rectangular shape out of the selected tile based on these coordinates.

Filled Ellipse: Places tiles in a round shape in the 2D editor. Works almost the same as the Draw Rectangle tool, but generates a filled ellipse shape instead.

Draw Line: Draws a line of tiles between the coordinates where the user presses down the left mouse button and the coordinates where they released it.

For bonus points, maybe also non-filled versions of the same tools?

(Apologies something like this has already been proposed; I haven't managed to find anything.)

I've been told that I can do this type of thing by holding Ctrl+Shift for a filled rectangle while drawing tiles and just Shift while drawing for lines, but I do not find this intuitive and would prefer to just switch between tools with a single hotkey press without having to hold down any keys.
