I’ll take a closer look later but for now will suggest this passed the beer test with flying colours 
So, with disclaimer for the user perception …
First impressions having skipped a couple of iterations recently:
- Web Hosting Manager has taken a great leap forward - the design is really good!.. I especially like the font sizes, which makes for easy reading. I would only push for one notch less gray…
- It all looks good and is simple to use.
- I note that I’m thinking about what I’m doing more than worrying about whether the network is working, which I think is a credit to the design and the responsiveness.
- Network is fast and upload of large files progresses well.
A few problems though mostly minor - the remapping being the biggest… and on Linux if that is a difference…
[Create new folder].[Upload files] on first use - doesn’t… it uploads file=[first alphabetical from the selection]… where there are more files, it requires user navigates back and uploads all but the index.html.
[upload from scratch]+[files] has no memory and each time defaults back to ~/
[Create new folder].[Upload folder] is annoying to make sense of. A website is top level content and subfolders; so, you want to upload [a site] not just a subfolder or a selection of files. Uploading the folder into the “new folder” makes less sense because the index.html is so important on first use. Better and easier to understand would be to adopt the content of the folder uploaded, not the folder itself - and that avoids the need for user to select all files in folder. However, the option to simply upload one subfolder is likely cause… but it’s a minor use relative to uploading whole sites… so perhaps needs to be made a third option along with [upload site]|[upload file]|[upload subfolder]. The problem with the current behaviour compounded because the remapping doesn’t work to compensate for that.
[Remapping] doesn’t seem to offer options to remap to a subfolder, which has been mistakenly uploaded and which then contains the index.html and top level documents… so, no option to reset map to lower level folder.
[Remapping] dropdown isn’t working beyond suggesting one folder - looks to be always the first one I uploaded. So, not useful for remapping atm.
[Create new folder].[Cancel] does not delete the uploaded content in the way perhaps expected. At least a warning or query “do you also want to delete uploaded files” might be appropriate.
Web Host manager’s sub window is not tall enough or fluid enough that the + and bottom detail is visible on first use; so, user has to take initiative to scroll down to find that. Given the + is root to upload files or folder that’s a bit more discovery that should be needed.
Probably something like OCD but I would prefer that the [Home] and [SAFE Hosting Manager] were self referential links not just static… I think that’s because it’s not obvious what it clickable and what is not; so, I want everything to be clickable, even if it’s just to confirm that this is the top level of Home… and I want to refresh the Home to close the expanded >PublicID detail.
I wonder the account status should be displaying in the Web Hosting Manager… rather hidden away from those uploading content.
Location with ‘root-’ seems odd where the service name exists… surely simpler to have as _public/PublicID/ServiceName not _public/PublicID/root-ServiceName
File upload=overwrite seems not available… delete and then upload seems unnecessary extra work
8/10 would use again
