Unable to reproduce because webui doesnt work for me on 0.9.0 cc @lidel, click by "Remove" button does nothing

[lidel]

@spylogsster I believe the remove issue was fixed in ipfs-webui v2.12.3 which should be included in 0.9.0-rc2
As a workaround, you can use "Remove" from the context menu behind right-click on a file
