As a Roblox developer, it is currently not intuitive that items in the explorer can be deleted that you are currently not able to see due to filtering workspace.
For example, if I am removing duplicate welds manually, I first searched for all the welds in the game using the Filter workspace feature
I see a handle as a parent of all these welds. I right click on the handle to select children, and then press delete. Now everything in the tool is removed -makes sense I used a legacy feature with a new filter option.
However, I think it would make more sense if what was selected in the above example in actuality would be this:
If Roblox is able to address this issue, it would improve development experience because of preventing loss of work. If I were not careful I could have easily kept going and erased many features of the game and I would have never saw them removing due to the workspace explorer being filtered.
