Hi,
1.> I was trying to upload some images in a business account gallery to test and it doesn't shows the attachment unless its Submitted (Saved).
2.> Can't upload multiple files at once, have to upload one file, submit it and then upload another file.
3.> Also the image shows some random words at bottom of every uploaded image (Not the actual file name). It would look good if either it takes the actual file name or shows no name or just shows 1 for 1 image, 2 for 2nd image, 3 for 3rd image, etc.

Thanks

1) yes, as you upload file via input
2) could not reproduced on demo, can select 3 files at same time with no issues.
3) Title of image should not be shown, you can fix this in user.js of plugin and change:
      getCaptionFromTitleOrAlt: true,
into:
      getCaptionFromTitleOrAlt: false,
