Lazpaint: Eraser tool brushes(lighten, darken,etc.) not working correctly.

[Love]

For make transparent, lighten and darken mode of eraser single stroke which overlaps itself will create noticeable differences. Can you make it not to paint pixels that are already touched while we have not released the mouse press. For sharpen and blur mode of eraser it is not needed in my opinion(It was fine for me.) Can you also add soft brush for eraser tool like you have done for paint brush tool. See the attachment.
Have a nice day lazpainters.
