You're double clicking on the title. Double-clicking on any metadata dispalyed allows it to be edited or deleted (if deletion is allowed for that type of data.) Single-click selecting allows the book to be deleted.

I don't know of many applications that use huge icons today. The lack of proportion between the arrow and the image is too important imo.

The option of resizing will be returned soon. That said, the icons were recently changed and the poll confirms that most users like them. I just don't agree with many of your comments about the UI,a nd to the extent that I do agree, they seem to be minor tweaks that won't improve my experience at all.

I believe that new users should not have to learn a whole bunch of new shortcuts. Reusing the ones they already know sounds much simpler to me. The default action when pressing the enter key in their file explorer (whichever os they use) is to open the file. So calibre should do the same I believe.

Generally, I agree that pressing "Enter" ought to do something - but what? There are two obvious choices - View the book and Edit the metadata. Actually, Calibre is a database, so the most logical action is not to open the book, it's to open the database record. That said, I slightly prefer having it open the book for viewing (i.e. duplicate the function of the "V" shortcut).

* The program shortcuts are frustrating: while keeping the current shortcuts as they are, for backward compatibility, you may want to use Ctrl+... shortcuts.

I disagree. I don't know why I would want CTR+V to be "View" when under Windows it means "Paste" CTRL+C in Windows is "Copy" but "C" in Calibre is "Convert."

* The program is overall too slow. Importing ebooks should be faster ; it could and should be made a background task in the first place, as in any music library manager. You could use the space on the bottom left to display the job currently running.

There have been numerous speed improvements in the last few months that have dramatically improved my experience with Calibre. That said, Calibre is optimized for rapid development. I think that's the right approach.

* There should be some way to update an ebook. Suppose you're working on a document, and suppose you want to proofread it on you ereader. Then you will inevitably need at some point to update the doc, as the writing advances. Having to delete, then retag the doc is a pain. There might be an option already, but then it needs to be more obvious (why not compare the file name of added files to those of files already in the library?)

I actually wrote code that did this. There's an option labeled 'If books with similar author/title found ... merge' When I wrote it, it allowed a user to simply drag a revised version of a pdf or epub into the GUI and it automatically overwrote the old pdf or epub. I was editing lots of books, and each time I did, I would simply replace the old version. I found it very useful. Kovid took it out before adding this code to Calibre. He revised it so that it never overwrites an existing format, it only adds formats that currently don't exist for the record..

After thinking about it, I agreed and now think he was 100% correct. To the extent possible, Calibre will preserve the ebook unchanged in the database and prevent it from inadvertently being overwritten with potentially the wrong book. Some of your other suggestions relating to automatic syncing seem to violate that basic premise.
