Hi danilHave a look at the extension in FileReference for example.��You will see how you can extend the default inspector.��What you should see is that you can use any Spec20 UI within the panes.��So we get the extensibility without the glamour and we gain the uniformity ofusing Spec20.��For us the moldability is important. If you have scenario that do not work we will study because��the current version may need some adjustments.��But what I can garantee is that we want to make sure that we can all build our own tools.��Here are the extensions we are using for a new compiler we are buildingOn 18 Dec 2021, at 16:06, Danil Osipchuk <danil.osipchuk@gmail.com> wrote:Dear all,Being a long time smalltalk user (meaning I'm crafting tools for my own usage for domains I'm working with) I always relied upon the environment itself to interact with models to spare time creating user interfaces.

Meanwhile pharo9 looks increasingly neat and I would like to make a transition but having tools in pharo8 holds me back.I would be grateful for any pointers to help me to get started with the moldable inspectors pharo9 - papers, talks, online discussions, etc. I can likely figure it out on my own, but having an overall understanding of the approach concept would save an effort and shorten the trial and error phase.(maybe I'm overcomplicating�� it and just having browsed around inspector code pragmas is enough to get started)regards,��Danil
