As a german, what I prefer about english spelling:
* You do not capitalize Nouns in your Sentences which is means I don't have to analyse the lexical Structure of a Sentence while writting stuff.
Stuff that is hard in English but rarely talked about because of the prominence of the phonetics-vs-traditional spelling:
* hyphenation (fairly complex, basically one needs to look it up or rely on tooling in english, rarely taught).
* punctuation, especially placement of commas
* capitalization in headings (a bit confusing, conflicting recommendations)
Oh and as for german there are a lot of strange things buried in what superficially looks like a fairly ok system.
* Typically you can infer from the roots of a word whether to spell with `e' or `ä' (i.e. schälen (to peel) is spelled with ä because it stems from Schale [peel]). But for some words that doesn't apply, for example Mehl (flour) is related to `mahlen' (to grind), but not spelled "Mähl".
* Auslautverhärtung is not spelled out but implied. I.e. Hund (dog) is kind of pronounced as if it would end with a -t ("Hunt"), whereas "Hunde" (dogs) has a soft d sound. Turkish makes such things explicit (compare `kitap` and `kitabi`). If we went down the turkish route, we could introduce a soft-s and hard-s distinction in the alphabet (maybe z vs s) and get rid of the `ß/ss` mess.
* `sch` should be replaced by Ş, w -> v (with existing spellings of v being replaced by f where necessary ("von" -> "fon"), z -> "ts", etc.
There is an obscure swiss organisation promoting a spelling reform for German(that differs from my suggestions) https://www.ortografie.ch
Its focus is a lot on vocal lengths and capitalization. Kind of interesting stuff (that will never make its way into the maintstream).
