i would like to see an easy entrance for both editors. Maybe an icon to get access.
Especially beginners can benefit from it but it is practical for all users.
For example, it took me weeks to come across jfxr for the first time.
Gdevelop should show what it can do, if you open it the first time.
In the appendix an example of what such a thing might look like.
One more: this could also be interesting, if LDtk will integrate in Gdevelop someday!
