My personal suggestions.

Okay these will be bullet point and then expanded upon.

1. FPS counter or any kind of counter to indicate when a user is recording a file and wen they aren't.
2. Have dual audio channels.
3. Also what the elgato has is a pretty cool feature. For example when you talk the game audio lowers. (This would just be a feature to have an isn't needed directly at this time)

1. Now to expand on what I said. When we press our hotkey button there is no indication to say if we are reording or not. This can be a problem for LP'ers ot twitch streamers who like myself have the key macro'd to their mouse button. I sometimes end up hitting the record key by accident and do not catch on that the recording has stopped.
2. This is a must. For me this is why I never used FRAPS (it's crap either way and always was) you can't lower game volume/boost mic audio in editing programs such as vegas pro. This is because the audio is mixed. So you either spend 30 minutes getting the sounds volumes right prior to recording otherwise you're going to have some serious problems. If this program had dual audio channels (more is better) then we can just record and then lower the game volume in the editing program. Saves myself and other LP'ers a good 30 mins.
3. This isn't really needed but it's good for if you want to retain a good focus of game sounds as well as your voice, instead of making your voice the primary source of sound that your viewer will hear.

These are must have options. And it's a reason that this software has not reached many gameplay recording people outside of livestreams. If you agree please votes with the phrase "Do it now. Please."

1. Recording status is indicated at the bottom of the program. If you have problems accidentally hitting the start/stop recording hotkey, use a more complex hotkey combo like Ctrl+Shift+Key. You can also use buttons on a different DirectInput device like a gamepad if it isn't already used by the game.

2. This is planned for OBS Studio, probably won't make it into OBS1.

3. You can enable audio ducking in Windows. Right-click on the speaker icon in your system tray and select Playback devices/Recording devices/Sounds (doesn't matter which), then click on the Communications tab.

When I'm playing a game there seems to be no indication. These features will also help with ease of use. Just giving my two cents on making the software more user friendly and readily available. I could make the hotkey combo 100 buttons but when it's attached to a button on my mouse it makes zero difference.

As far as i know this only affects incomming communication.
