Tested with Firefox and Chrome and watched for DOM changes and after a minute the checkboxes were still selected. Even If I run an asynchronous task in another Storage Pool it won't change the volumes in another Storage Pool. I am saying, when you are in the storage volumes list view without any storage volume selected and switch to the gallery view, all the storage volumes appear selected for a second and then the page is refreshed to deselect all them. Do you mean that black border that appears for a brief second? This is not happening on Chrome but Firefox and IE indeed have this problem. I suspect it is because of the border-color transition to "transparent", as Chrome supports RGBA while Firefox and IE only supports RGB for transitions.

Once the wipe process is completed the line is updated with 0.0B in the allocated column, however the parent %Used and Allocated columns are not refreshed. Are these two the only fields that should be updated? Should it be done for Clone and Delete as well? I was talking about the storage volume settings. When I do wipe multiple volumes, only one of them get the settings updated. I've selected five different .qcow files and wiped them. According to chrome the list refreshed 6 times, the last time when the selectedVolumes array is empty. For large files displaying in MB when I wipe them, they immediately turn the "allocated" column to 0.0B but If I choose to wipe a file in KB, the allocation and capacity has the same value: Before: { "allocation":131072, "isvalid":false, "capacity":127314, "name":"0003-WOK-Deleting-unecessary-files-conflicting-with-new-u.patch", "format":"raw", "has_permission":true, "path":"/root/Downloads/0003-WOK-Deleting-unecessary-files-conflicting-with-new-u.patch", "used_by":[], "type":"file" }, After: { "allocation":131072, "isvalid":true, "capacity":131072, "name":"0003-WOK-Deleting-unecessary-files-conflicting-with-new-u.patch", "format":"raw", "has_permission":true, "path":"/root/Downloads/0003-WOK-Deleting-unecessary-files-conflicting-with-new-u.patch", "used_by":[], "type":"file" } They keep the same value for allocation and capacity. With a large qcow file: Before: { "allocation":1014439936, "isvalid":true, "capacity":8589934592, "name":"2c2f4ef0-7ce0-4aad-b6c8-b891d21fbf40-0.qcow2", "format":"qcow2", "has_permission":true, "path":"/var/lib/libvirt/images/2c2f4ef0-7ce0-4aad-b6c8-b891d21fbf40-0.qcow2", "used_by":[ "vm1" ], "type":"file" } After: { "allocation":0, "isvalid":true, "capacity":1014497280, "name":"2c2f4ef0-7ce0-4aad-b6c8-b891d21fbf40-0.qcow2", "format":"raw", "has_permission":true, "path":"/var/lib/libvirt/images/2c2f4ef0-7ce0-4aad-b6c8-b891d21fbf40-0.qcow2", "used_by":[], "type":"file" } Note that the wiped volume capacity has a little bit more of its previous allocation. Is it correct? About what you said, I agree we should update the storage pool settings as new volumes or deleting volumes may change the storage pool allocation. I think only %used and allocated must be updated. Ok, will create a new function to replace the old values. > 7. The scroll bar should only scroll the volumes. It is hard to get back all time to have the Actions menu available. > > I'm ok with this for the list view appending a scrollbar on the "table" element but with the Gallery view I think it looks odd. See attached screenshots. IMO It is OK for me on both views (list and gallery). Do you have any other idea to have the same behavior on gallery view which does not look odd as you said? I was trying to attach the scrollbar on the same position as it is today but this doesn't work well with just CSS, I would have to write some lines in JS to keep this parallax effect. I'll keep the same as the screenshots but with different max-height values for list view and gallery view and the scrollbar attached to the tables.
