BorderlessMinecraft VS PixiEditor

Yes

I'm late but I develop Borderless Minecraft, an app for running Minecraft as a borderless window that is used by quite a few speedrunners: https://github.com/Mr-Technician/BorderlessMinecraft

not a mod but a app https://github.com/Mr-Technician/BorderlessMinecraft

You can use borderless minecraft to run minecraft in windowed borderless mode so that it doesn't freeze when you alt+tab. I'm not affiliated with the program in any way but I've found it extremely helpful so I'm passing it along.

theres a program that makes the game windowed borderless for you https://github.com/ThatFlashCat/BorderlessMinecraft/releases

this should work

If none of this sounds appealing, the only other suggestions I have are either find 3rd party magnifying lens software or to search for a new pixel editor. There are some newer pixel art editors out there, such as Pixelorama, PixiEditor and PixelMash. There are also general raster image editors, such as GIMP and Krita. Other suggestions are listed on Lospec.

Yeah, https://github.com/PixiEditor/PixiEditor

https://pixieditor.net - a pixel art editor, I've been making it for about 5 years. For last 2 years 2 people joined me and we've gained about 5k downloads. We have big plans for it. We have open collective, but unfortunately no donations yet. It will always be free and we want it to be like blender, but in pixel-art world. There will be full featured animation suite, cross-platform and most importantly, user friendly :)

You can check pretty good software list here. There is also new, small but devoloping software, named PixiEditor. If you know how to get stuff from Github, here is the link.
