The following hidden gems are new to LabVIEW 2018:
Note that for LabVIEW 2018, there is not a new Hidden Gems package on the Tools Network. Version 22.214.171.124 continues to be the latest version.
So many great examples of defining an interface for extending the inbuilt LV functionalities with your own algorithm details (lambda functions), defining object oriented types etc. yet nothing provided as a real interface, making it impossible to actually extend this and provide your own types. Why is it that smart steps in the right direction get hidden and buried? Why not just do it right once, and not these timid steps behind the scenes? These kind of features should have been in LV 10 years ago.
Will these show up in Quick Drop in another release?
I have not yet assessed whether there will be a new Hidden Gems package for the NIWeek 2019 release. I can say that LabVIEW 2019 includes a 'Synchronize Data Flow.vim' in the Synchronization palette that is an updated version of the Sync.vim hidden gem I mentioned above.
Also note that even if we do update the Hidden Gems package, we probably won't include palette entries for files in the examples folder.
