Late as usual,  [sorry]...  I have been using geany for years, it has json and dozens of others, including OpenSCAD, I always have geany open with OpenSCAD libraries, instead of opening the libraries using OpenSCAD, which just messes up the recent file history, because I have a rubbish short-term memory, I can set off to the workshop/shed and have forgotten what I went for by the time I arrive. https://wiki.geany.org/config/json Usual things apply, cross platform, open source. Fabulous. If anyone is interested, I also have a Recent Files application, developed from recused.py, originally found here, https://askubuntu.com/questions/803869/is-there-an-indicator-to-quickly-access-recently-used-files which ONLY lists OpenSCAD files, because Debian's recent files application is a joke and has an even worse recall than me. The current version is here https://codeberg.org/rogerw-codeberg/RecentlyUsed Roger.
