Feature Request: Use LSP preselect field of CompletionItem to preselect most likely item with the same prefix

[Colengms]

With typing in the body of a function (not member completion), when I type e, the most likely thing I want to type is else. What I'm offered is:

ecvt is a function in stdlib.h. The others are macros from dlgs.h in Windows SDK.

It seems much more likely that what I want to type is a keyword, and not a specific global function name or macro.

It looks like LSP provides a way to present the most likely candidate instead of always navigating to the alphabetically first option with the same prefix.

The right way to decide a best candidate is debatable. It seems like it'd at least be possible to assume keywords (or certain keywords, such as else and if) are more likely than function or macro names, etc., in the body of a function. Perhaps else would be preselected only if the previous lexical token is a close curly brace.
