Can't distinguish whole word sometimes

[AstroWYH]

eg. wyh wyh-a it can't distinguish.

although I know it can recognize between wyh and wyha, but I also wish u can add a clear feature, case sensitive and whole word, thanks~

[AstroWYH]

The feature wrap around I just want for a long time, I hope u can add those two above, sincerely.

And another issue, compare to the origin, it has a little delay, hope can optimize.

[AstroWYH]

sry, wyh and wyh-a，it should be like that, there's no bug~

It's realy nice, if there's also a vs code version, that gonna be great!
