Description of the new feature / enhancement
Information of OU/OS
OpenUtau Version: 0.1.529.0
Operating System: Ubuntu 24.04.2 LTS.
This is mostly a Quality of Life change.
Currently, expressions can be added manually or automatically via the GUI in the Expressions editor.
For the automatic version, a .yaml manifest file of the resampler flags is needed in the same directory where the executable of the resampler is located with the name "name_of_resampler.yaml" such as it is shown in this example in the Wiki for Moresampler.
However, if the .yaml is badly formed or some expression is not valid, no error is thrown out for the end user and it only appears on the logs, thus it fails to notify the end user of this fact and makes the Add all expressions suggested by renderers button in the Expressions editor to silently fail.
Proposed technical implementation details
When looking at the source code, I think the best solution would be to add some kind of error window pop-up on the ResamplerManifest LoadManifest function
