How many of these problems can be overcome by simply running the tools in the browser and not as standalone apps?
However, for real desktop tools that utilize the operating system's bells and whistles, which truly make an app a desktop app—like Sublime—I'd never use an alternative in the browser.
I such cases I would also never favor an Electron app posing as native software.
Arc seems somewhat resistant to large memory grab issues, but the Notion database kills it as well.
