Heeeey, i have a bunch of suggestions, feel free to add them or not.
>A way to hide the group menu and show the sprite in fullscreen. Often I'm using your tool to check if I forgot to draw an arm variant for some clothes, so what I like to do is just take a screenshot of the sprite, draw over it in Photoshop the sleeves it's missing and export the image that I add over it in the layered image lol. But sometimes the arm is cropped out. Also maybe being able to change the background color?
>This one is probably hard to implement, but I like opening your tool when writing dialogues when I'm not sure which expression to use (I have it on a keyshortcut). So when you open the menu, it would be great if it could update the sprite with the attributes of the currently shown tag lol (if it's actually being shown). So when I open up I can see instantly my sprite and the different options without having to manually clean and choose all the attributes.
Have a great day!
