You can now browse your entire sdcard for samples when loading a sample (not just locked to electrum's samples folder). This will save space on your device - allows you to put all samples in a central location. You can also load ReLoop samples by browsing to "/sdcard/reloop/samples"
Exporting has been improved now, with a better browser, which allows to you save the exported file anywhere on your sdcard, as well as see the names of other exported files
