Seeing this thread here about the TL client and support for other platforms, I want to also express my/our wish to get the TL client to support more other platforms and definitely also aarch64/arm64.
In fact, IMHO it would be a great move - and probably best - if cendio could consider to open-source the client and move development of it to, e.g. GitHub so that interested third-party developers (like me) could contribute / develop own client versions and also potentially merge these changes back via pull requests.
IMHO the ThinLinc infrastructure could benefit a lot from open up more regarding open source and public development on GitHub&Co. And especially the TL client should be somewhat uncritical to open the development, which could help to significantly increase the community around ThinLinc (which is still rather small given the great technology behind this product!).
