Wow, the tool for decomposing characters is very cool! I assume you are talking about the thing that appears, when I click "Matrix"? I think it would be good to have "decompose characters" somewhere. But I might actually use this to get the component characters. In my app in my vocabulary file I also have tags for words, which are like "component:<component here>", so that if one knows how parts of a character, one could also search for it, without knowing its pinyin, by searching for "tags contain component1 and contain component2 and ...". I might add more component tags using your tool.

What I noticed though is, that some of the components don't seem to be like what I would expect to be shown as components. For example I tried the word 衣服 and 服 is shown to have the component "二". I guess one could see it that way, but some other dictionaries stop at 月 which itself is a component with set meaning (moon) and usage as radical (often for body parts). My favorite online normal dictionary for example: https://www.mdbg.net/chinese/dictionary?page=worddict&wdrst=... (hover over 3 dots of character and click the button with the 字 and scissors to see decomposition) says:

    服 = 月 + 𠬝
    𠬝 = 卩 + 又

A Chinese teacher told me there are various approaches for decomposition, so this might not be a science or that rigorous, but I think consistency would then dictate, that you decompose "二" as well. I don't always agree fully with their decomposition either and usually I stop at any component, that still has meaning by itself, which can be pretty low level 1 or 2 strokes components already. For determining that, I also use information from a language school, which I copied into a repo: https://codeberg.org/ZelphirKaltstahl/language-learning/src/... "All radicals from their website". Also useful for memorizing the characters, if one can derive a mnemonic for a character from its components and their meaning.

The advanced UI looks very complex, but I don't mind that. In fact it is quite cool! Just has some stuff I don't even know what it is about. I noticed, that once one toggles the advanced UI, I didn't find a way to toggle it back to simple again.

Bookmarked!
