As the title says, the ability to modify tokens or other textures would be great. I don't need pixel by pixel manipulation, I want basic cut at this pixel to this pixel. For example, I want to vertically slice a map tile in half. Select the middle pixel and perhaps an option for vertical slice, or the pixel on the opposite side you want the slice to end at. Then Roll20 slices the texture and gives you two objects. Along with this, I'd want Roll20 to keep the 'half-tile' configuration, and allow me to flip its orientation inside the grid space it will snap to (i.e 2x2 grid units for a table, one half table 2x1 the other half another 2x1. I want to be able to flip the left side of the table to be the right hand side and vice versa. I also would love for it to work with stretched textures too, for example stretching the table from 2x2 to 2x4 then slicing so that there are 2 2x2 pieces of the table.). Hopefully that illustrated what I am trying to get at. One main thing I'd use this for is making diagonal tiles in Roll20 so I wouldn't have to move to an outside program to accomplish this. Alongside this suggestion I'll add a bonus for being able to tile a certain texture on the whole map, or in sections of the map that I select. Say, for making a desert, select one tile, or a set of tiles, and Roll20 will fill in all blank tiles in that same pattern across the selected board space. Feel free to add on to the idea, just tossing some things in as I'm starting to become familiar with Roll20 and all its glory.
