@Kust that is exactly what I have wanted for a long time, however, that would be inconvenient for many.
We could bring back some signs, such as the “Ѣ”, which has reflected differently.
So, for example, we would, in that case, all write the word “place” as “мѣсто” [město].
However, if we would do that, the language wouldn’t be phonetic at all, since there were lots of sound changes which happened in the Slavic world.
In a larger scale, this wouldn’t work at all, but, however, in a small group (such as this community), it is doable.
We could develop a conlang. 🙂
