2) Yes, you can share, but you can not transfer ownership from your workspace to other guy workspace. For example you leave the organization or project - you still have the right to delete/edit gotiggr project if you previously created it. Google docs for example allow you to set new owner of document - then you are no longer owner of it but you can edit it until new owner cuts you out.
3) I meant element "a", attribute "title" - http://www.web-source.net/html_mouseo.... I would like to put some clarification/specification on some control (especially link or button) - but want to avoid clouding and spaming whole window with callouts. So I put my clarification in title - and other users on web prieview hovers mouse on - and sees the clarification text. There is a workaroud - on page - I set event OnLoad and action - set HTML Attribute for control "title" with my value. But this is inconvenient if you have many controls with titles. Button or text does not have OnLoad event just OnClick. So maybe it is easiest way to introduce onLoad event on controls, or just add new property - Title? But title is plain text, maybe we can consider rich text hint/callout...
4) I found that I can create on Click event and navigate to some link - that is what I want. So please ignore this suggestion.
5) One more suggestion - order of screens. If my screens follow some logical sequence, I can not reorder them. Also I can not insert screen in particular place of screen list.
