2.0 was released 20 years ago in 2004… a lot of things, including software, can change in 20 years. 3.0 finally has adjustment layers, et al. that they have been working on since I first started following in 2008 but had blockers on GEGL & all sorts of massive refactors… which are now finally coming. If there was a time to try to get a new opinion on GIMP, it will be now (or very soon when 3.0 is finally officially released).
