Thanks for the valuable feedback.
I hear you - the biggest problem (and has always been the problem on Vortex) is that feeling when you accidentally skip past a pokemon that you really wanted.
There's a few ideas floating around on how best to deal with this problem. We have to keep in mind that introducing some sort of mechanic to slow down the encounter rate, or halting movement on encounters, can make the game annoying in other ways. Personally, I find that forcing players into an encounter every few paces like the original games is probably one of the worst features of those games. An auto-stop toggle would mitigate this, but you might not always be in the right mode when searching, or you might get tired of the constant stopping and turn it off despite the risk - then back to square 1.
I think there may be some better solutions out there. We'll try to find the best compromise.
