No. I didn’t make it I started this topic to actually verify how big is a group of people being hit be the 128kB limit for user app on the electron as of December 2020. There already were a couple of topics regarding this limit (this being my favourite) and it seems that in fact it is possible, but would require heavy lifting in device-os and the build process. And even so in the end the changes would need to me merged into the official device-os release. Otherwise the automatic update process for product based devices would not work as expected.
Please give a like to this topic or leave relevant comment if you find 256kB user app a helpful feature. I’ll try to fill in the feature request, thus this poll.
