A "fill all of same colour" tool

[noble depot]

Something that would change every pixel of a colour into the selected one. It's really annoying when you have to recolour a sprite, but all the pixels you want to recolour aren't connected so you cant use the regular fill tool and you instead have to go to every little pool of the colour and change it.

e.g: click on a red pixel, have blue selected, and then all the red pixels in the canvas change to blue.

If you don't know what I mean, just look at the "Paint pixels of the same colour tool" on https://www.piskelapp.com/p/create/sprite

while sparate tool would be very useful, you can already do that with Color replacer in palettes window

I just noticed that a "replace" option appears when you right-click a colour in the palette
