I was wondering if it would be possible to implement a search function in the dialogue window that pops up when e.g. moving a collection or within the workflow for file collection.
For 'move to' function: At the moment we can only see the project titles, but it would be easier to search for the property 'Study Source ID'.
For the 'collect files for genestack upload' wf: At the moment there is a limit of the number of collections displayed in the dialogue window, a collection not within this limitation cannot be selected. Collections also cannot be marked as favorites. Maybe this could be an alternative to creation of subprojects / changing the workflow itself.
