I thought pause/resume was a basic feature. Turns out it's our main differentiator

Short summary

Pause/resume emerged as Simple Screen Recorder's unexpected differentiator—a feature the founder didn't recognize initially but users instantly valued over competitors. Five technical lessons: spring-based physics animations create better UX than linear easing; Chrome MV3 requires Offscreen Documents for background work; visible state controls beat hidden logic; local-first positioning matters more than features; OPFS eliminates server dependency. The tool launches free, cross-platform, fully client-side.

• •Pause/resume became the main differentiator—an overlooked feature that solved real friction vs competitors like Cursorful
• •Spring-based animations over linear easing; Chrome MV3 Offscreen Documents; visible UI state prevents perceived randomness
• •Local-first positioning and feature visibility matter more to adoption than underlying technical sophistication
