A simple improvement that I would love to see in leitzentrale is the
ability to create launchers from the GUI.
Aside from that, with the recent changes to libc, has QProcess been enabled
in Qt5? Because that's perhaps the biggest remaining issue in porting
existing Qt software, if the new SDK solves the qmake-related problems.

> For the road map 2019, we picked "bridging worlds" as our guiding theme:
> (1) Lowering the friction when combining existing software with Genode,
> (2) Fostering interoperability with widely used protocols and APIs, and
> (3) Making Genode easier to approach and generally more practical.
> With respect to (1), we identified Genode's custom tooling (build
> system, run scripts, ports mechanism, depot tools) as a point of
> friction. They are arguably powerful and flexible but require a lot of
> up-front learning. This is certainly a burden unacceptable for a casual
> developer without a black belt in Make and Expect/Tcl. The new Goa tool
> rearranges the existing tools in a way that puts the concerns of casual
> developers into focus, allowing for the use of commodity build systems,
> eliminating Tcl syntax from the equation, running sub-second test
> cycles, and streamlining the packaging of software.
> On account of (2), we switched to C++17 by default, fostered the use of
> Java, updated Qt5, and put POSIX compatibility into the spotlight. We
> were eventually able to dissolve the need for our custom Unix runtime
> (Noux) because all features of Noux are covered by our regular libc now.
> Our biggest step towards (3) is the https://genodians.org website we
> started in winter 2019, which gives individual members of our community
> an easy way to present thoughts, projects, and experiences.
> Complementing Genode's formal documentation, it also conserves practical
> tips and tricks that were previously not covered in written form.
> When speaking of "bridging worlds", I should not forget to mention the
> tremendous effort to bring Sculpt-OS-like workloads to the 64-bit ARM
> world. Thanks to the added support for multi-core AARCH64,
> hardware-based virtualization, and network/USB/graphics drivers for the
> i.MX8 SoC, the flexibility of Sculpt OS will eventually become available
> on PC hardware and ARM-based devices alike.
> Over the course of 2019, we admittedly skipped a few topics originally
> mentioned on our road map. In particular, the user-visible side of
> Sculpt OS received less attention than originally envisioned. We also
> deferred several ideas we had in mind about reworking our GUI stack.
> Instead, we expanded our work in the areas of storage (block-level APIs,
> test infrastructure, block encryption) and input processing. This shift
> of focus is mostly attributed to the priorities of Genode Labs'
> customers who fund our work.
> Drafting plans for 2020
> Hereby, I'll just present my personal interests and invite you to do the
> same. When carving out Genode's official road map for 2020 until mid of
> January, I will then try to condense all the input into a tangible plan.
> Personally, I think that after "bridging worlds", it's time for "use,
> consolidation, and optimization".

> - Making the Leitzentrale's layout more logical
> - Keyboard-based navigation
> - Context-aware on-screen documentation
> - Settings embedded in the graph nodes of the runtime view
> - I see plenty of opportunities for optimization throughout the entire
> software stack. With the rich C runtime in place now, it becomes
> easier than ever to stress the system from various angles, which is
> a great motivator for optimization work.
> - Genode's binary compatibility across a variety of kernels is a key

> Such a consolidation would make Genode less reliant on the subtle ways
> how edge cases are handled by each kernel (in-kernel data structures,
> capability re-identification), and reduce the amount of kernel-

> This is merely my personal point of view. Now I'm very interested in
