Thoughts:

• Easy to use.
• Useful search ability (didn’t find any other tools with this). Helped me find the palette in a savestate for Oracle of Ages.
• The slider bars are nice for direct manipulation (surprisingly many other palette editors lack this and require typing in values).
• It can load the entire file for editing, whereas many other tools only load the palette and require you to know exactly where you are extracting/inserting it.
• Although it’s called “SNES Palette Editor”, it also works with {Gameboy Color, Gameboy Advance, Nintendo DS}, which all share the format r5g5b5‌x1. It would be cool to generalize this tool even further by extending it to other console palette formats (which would obviate a number of other one-off console-specific editors).
• Should display more colors (the entire line above and below), not just the next 9, since there were multiple matches in the search results that shared the same first 9 colors. It would also be valuable to print the address immediately below the palette in the currently unused ruler.
• Changing the current color offset by clicking the up/down arrow buttons in the offset field is tedious. We should be able to change it by just directly clicking in the palette on a different color.
• Tab key order is wonky.
• It lacks any import/export (such as JASC, Paintshop Pro, Gimp, RIFF), which would truly complete this tool.
