I feel your pain.
I didn't wanna learn OBS either, but the VFX tutorials I've done just required so much post work (sometimes dozens of hours) I wanted to simplify things. Once one gets past the learning curve it becomes easy to switch between screen windows, call in overlay graphics, and normalize audio on recording.
Hell, I bought a Elgato Streamdeck. The "Mini" version is $80. What does this do? Oh, it's a little controller with 6 buttons (there are 15 and 30 button versions) with little OLED screens in each button. It can be programed with varied tasks for more-or-less any program, but, for specific streaming purposes one could set up dedicated buttons to start/stop recording, bring in/out any pre-made graphic overlays/title screens, switch between inputs (like between Roll 20 and whichever rulebook is in another Window)... Or just roll your dice. It's mostly macro programing, so, whatever! I own the 15-button version, but my last recording setup has me being recorded on PC 1, the software being taught on PC 2, my lower thirds/intro/outro media on PC 3,and a Blackmagic switcher taking the final mix and outputting that to PC 4. Good thing I use laptops! (PC 3 and 4 are tiny 12-inchers. The other two are 17".) So, in my case I was able to start/stop recording start/stop streaming (I was gearing up to do livestreams before the move), switch between full-screen me, full-screen of the app I'm teaching, split screen/pip me/app, trigger lower thirds, etc. Then again, my Blackmagic ATEM switcher was recording all the iso feeds from cameras and varied inputs as well as my switched output, and an edit list for DaVinci Resolve (yup, I was gonna switch my main NLE from Vegas to Resolve after 23 years) for easy post editing. The EDL would give lined up source feeds and a switch track on top, so if I wanted to re-edit its all right there for me.
Red wouldn't go anywhere near that elaborate, but he wouldn't need to for a game demo or play session stream. He's not putting himself on camera, either. Hell, *I* don't want to be on-camera (ironic the former actor hates being on camera), but, for what I was doing, on camera segments are expected. I was trying to grow my channel. At 10k subscribers, the companies whose product I was showing would be willing to discuss some sponsorship. A few bucks would be nice.
