I’ve never been able to use the app without setting it to use more memory, e.g. with 20K files on a network share I have to set the memory to 2GB.
The user experience with too little memory is not great, either files fail to load (defaul settings), increase and start again (1GB), then during tagging it would complain again about too little memory, now what (set to 2GB and restart).
Why not set the app to use all memory, like a native app would have, the memory would be paged out anyway?
