Hi Pekka

OK, so we now where the development diverged and the branch between Jolla
and Ubuntu (now Maliit default).

It will surely require time and, in ideal world, is a needless duplication
of an effort in a small OS which has many other components that would need
more attention. I agree with that aspect.

Indeed, we have now the input method that links presage to jolla-keyboard
written by @martonmiklos. We could probably go a long way by expanding
Presage with correct handling of Unicode string, implementing tokenization
in Presage to support more languages and exposing this functionality to the
plugin. This work can be reused then by any keyboard, not even limited to

Indeed, it depends on the priorities. Personally, I am interested in
developing open-source prediction/correction engine since I am using a
ported device and want to have good and working solution without Xt9. Throw
in the fact that Estonian probably doesn't have Xt9 support and you have my
main interest formulated. However, in the background, I also like our
approach since we rely on open-source libraries and this is transparent to
the users community as well as gives us an ability to reuse the components

When talking about one of the main user-interacting component in the OS,
such as keyboard, the transparency does become an important part of the
discussion. Large fraction of jolla-keyboard code is in QML and we can see
what QML is doing, if we wish. However, there is a library blob which I
have no way of knowing what's going on there. All I can see is that its
linked to all kinds of other libraries through its dependencies, including
network libraries as well. So, its essentially comes down to the trust that
the version that I have installed on my device doesn't call somewhere with
something. The trust that I do have at this moment. But I do find the
situation far from ideal and would prefer to have open stack for myself and
all other end users in the core components of the OS. In particular, the
parts which are used for communication and user input.

So, when we talk talk about longer-term plans with the keyboard, it would
be important to know whether jolla-keyboard is scheduled to become
open-source component in foreseeable future or not. If it is not then I
presume we should have a discussion within the community on what to do
about it and whether anyone wants to work on adapting open-source
components. Which, in the end, is the burden for the community that would
lead to investment of time and effort that would come at expense of work on
