Not too much in this update due to a few factors. I am going on vacation next week so I wanted to get what I had out there, and secondly my plan for the deleting playlist / file / folders capability uses something new from google that is still in alpha and would require me to upgrade pretty much all the android support libraries. Android studio 3.2 has a built in option to auto convert to use their new jetpack components, however 3.2 is still a RC and I wasnt able to upgrade from 3.1 in an easy enough fashion to make it worth my time.Deleting things in GMMP involves more than simply removing the file. The database has to be cleaned up and the queue order / positioning needs to be adjusted to account for any removed files. Since I did not want the user to have to sit there and wait with a spinner in front of the UI while all this happened, I plan on leveraging a new library from google called the WorkManager . Delete jobs would be created and set off to the work manager to get done in the background. Tag editing is also another thing that can be time consuming so I also planned on doing the same for that. This will make mass deletions or mass tag edits much more user friendly.I am expecting all the tools / libraries to be final in the next few weeks so that should make those features doable for alpha 5Alpha 4 is mostly on search enhancements and a few bug fixes.Feedback Forum Post:Download:Alpha 4 (08/28/18):New:Added filename, folder, bookmark, and playlist file search categoriesAdded multi select options to search resultsSearch will now show text saying no results found when a search turns up emptySong search results will have the song info option in the context menuAdded ability to give external storage write accessRe-added 'Restart On Skip Back' settingFixes:Multi select should no longer refresh the entire list each time after an item is selectedDefault playlist storage is now scannedFixed start scan setting in the simple settingsFixed sorting in the playlist file listFolder view no longer requires hitting the back button twice from the root view to return to previous viewNext audio source not always set correctly
