Instead of showing a splash screen, we will instead show a welcome screen displaying:
Plus any other functionality that seems sensible but doesn't unnecessarily clutter the UI.
This is less for the 0.x series but for the frontend rewrite:

Gimp is very slow to load, can some of this loading be done lazily on demand? Or in the background while the user can be preparing their workspace, opening a file and zooming in. E.g. Effect plugins maybe don't need to load until the effects menu is opened.

Once 0.2.0 is released (we just rebased on 2.10.18), lazy loading is something I could potentially take a look at. A balance would need to be struck between faster start times and keeping the application responsive imho.
As for replacing a splash screen with a welcome screen, that鈥檚 something the Glimpse NX team is working on for their rewrite.
