Preferred way to install unstable app in LEAP

Hello,

I have LEAP 42.1 and would like to install a new version of an app, in this case darktable.

What is the preferred way?

Can I do a one-click install of the required packages on https://software.opensuse.org/package/darktable without subscribing to the whole tumbleweed repo? A click on the Tumbleweed official release offers me to subscribe to the whole Tumbleweed oss repo.

Is there a manual way of doing - say - enabling only the required packages in the tumbleweed repo, or any other way I don’t know about?

Thank you in advance!

It looks like there is an “unstable” v2.03 which I assume latest, found in a community “graphics” repo for LEAP at
https://software.opensuse.org/package/darktable

I’d recommend that over installing something from a TW repo.
