It is a very decent file explorer without a lot of the recent additions that MS imposes (ribbon, slow display of folder contents &c).
Before I found RJTextEd I started .js coding using the Context editor and when that was abandoned by its developer, I searched for an editor replacement and found RJTextEd, it felt as if it was the natural successor to Context. RJTextEd has grown enormously since then.
Which brings me to CubicExplorer.

There exists a small possibility that Rickard might find that CubicExplorer could be 'revived' in a similar fashion. It is written in Delphi (mostly) and needs a new master, the previous developer having abandoned it too. It is fully functional, I often prefer using it to explorer, no slow loading, not affected by shell crashes, no bloody ribbon. I know that Rickard has loads of Delphi experience. It might be a match! I do realise that Rickard has a lot on his plate already.
There is quite a lot of shell work within RJTextEd that might find a similar parallel within CubicExplorer, it could form a basis for something new, perhaps RJExplorer. I would like to revive CubicExplorer myself but I also, have a lot on my plate and my skills in Delphi are near zero.
Just a thought.
