I 100% understand the gripe about why the fill tool is set to have antialiasing by default, that is deranged, but not wanting to have layers is equally unreal to me, layers are so useful, any image editor that doesn't support layers is a glorified doodling simulator.It reminds me of when they released Paint 3D and suggested it would replace MS Paint wholesale. The outcry was big enough that they didn't get rid of MS Paint in the end.
I can understand their desire to add a layering option to MS Paint, that's just a natural extension of any art-related computer programme, but other than that it really is a case of trying to fix what isn't broken. In any event at least the core functions have remained the same, which is why I've always preferred it. I've been messing with PDN today out of desperation but holy hell it is a shitty programme for what I want to use it for.
People keep talking about shit like "layers are so useful for X" and "the Y function is so useful to do Z" but I don't want to do X or Z. I literally draw all my borders pixel by pixel. I use the blank rivers basemap and an old topographic map as reference points and just make it up as I go. I borrow from historical borders where they make sense and copy/paste them over to either be slightly altered or left as is. The only tools I need are copy/paste, pencil, and the fill bucket, and I'm a happy man. I'm so very disappointed that MS Paint just doesn't seem to want to work for me anymore.
