Right now, the max memory is set to 200M: -Xmx200M

To increase this in the build, it can be changed in in ui/ui.gradle.kts:

jvmArgs.setAll("-Xmx1024M")

Otherwise, if you're needing to change it in an already-built application, this setting ends up in GRIP.app/Contents/app/GRIP.cfg. There, it appears as:

java-options=-Xmx200M

which can be increased as necessary.
