This is an issue discussed since early beta of Xojo and the corresponding Feedback case 24694 must be made accessible to everybody (it is still beta only).
As an example: When I want to check where I instantiated a class throughout my code, then this Find option in RealStudio was very handy. Now I have to open the Search Panel and manually type in the name of that class…
This is not a feature request but a regression which we need to have fixed ASAP.
If you share my opinion, please support Feedback case 24694
