Hello, first of all thanks for the awesome work and great product!
Our project uses meta-data quite extensively however the url querying/filtering can be challenging to remember and difficult for non-technical users. It would be great if we could define custom filters that present themselves in the pipeline UI, and pipeline viewers could click on them to apply the custom filter to the jobs shown.
The alternative is to create urls to navigate to the desired filter and have our users access them via a separate mechanism, or create separate pipelines for the various meta-data concepts we have defined (which is more work for myself to maintain them)
