Welcome to the community. Please be aware, there is no team so to speak. Poor @vlads is carrying most of the water right now when it comes to engineering (and everything else).
Regarding your post:
editor - This is no visual editor and one will not be coming any time soon. In my experience creating games and interfaces is already very efficient and can be done with very little code.
CTRL-R Stuck - What version of Solar2D are you running? I haven’t seen that issue for quite some time. Also, are you running a demo and seeing this issue, or is it your game/app?
Text Support - This is also unlikely to change. Solar2D is focused more towards games and less towards apps. Note: If you really need this, you can do it yourself, by editing the source, or making a lua library. I made a MLText module a long time back as an experiment:

FPS Data and Other Tools - You can easily make this and I’ve done so before. Right now, users can use my free FPS meter and MEM meters here: https://roaminggamer.github.io/RGDocs/pages/SSK2/libraries/meters/
Also, there are tools out there already for profiling, etc. You just have to look for them.
While there is no longer a maintained project, peek at the video to see graphing tools can be made:
