It's good practice to include screenshots of UI changes so reviewers can understand the UI impact without having to pull the branch and spin up the app, can you do so here, please?

Pressing Reset during training creates havoc.

I suspect that this is triggered by the reset process deleting the model directory, causing the log process to fail due to missing file (can't open the file), causing the reset to fail. This has flow-on effect such as the data and the interface getting out of sync due to dataset data being deleted but the dataset.json file remaining.

Could be fixed by monitoring data-processing, training and transcription processes, but that sounds complicated.

May be able to catch 500 status due to missing files and update the GUI accordingly?
