I have two wishes for Writer's Word Completion, which I think will be great improvements.

First, that all eligible completion candidates are shown in a vertical popup menu, to be immediately assessed and then accessed simply by the up/down arrow keys. Even simple text editors are set up this way, and it is far more convenient and effective than LO's current scheme of using ctrl-tab to cycle through unseen candidates.

Second, the collection list should be optionally persistent across sessions. Currently it is wiped when LO is closed. I can understand that this might be necessary for some for privacy reasons, so it should be an option.
