Feature request: Russian stressed vowels

[Malego1]

Use Cases

I study Russian, and stressed vowels are extremely important to learning words properly. I keep a personal dictionary of words and can not continue building it properly at the moment.

Proposal

The Gboard implementation is perfectly fine. For each Russian vowel (а, е, и, о, у, э, я, ю, ы), add a long-press option that adds an accent mark (á for a, etc).

As a native speaker, I really miss this feature too. I know that you can use custom xml-based layouts (iirc), but imo this should be in the default one.
