Allow all metrics as columns in my portfolios - ROA, ROE, Upside, Margins (Operational, Net, Gross, etc). Basically everything you show in the "Statistics" section should be available as data columns.

Also allow us to create custom formulas, ex: I want to have a column showing % above below 1-yr Target Price, AKA Upside or Margin of safety.

This are basic things - Why giving me 30% of all the info you hold as columns and not 100% of the info you have available? The very least give us the key metrics from your "Statistics" section for each company.

And you will kill everyone else if you add more chart columns - Day chart, Week chart, Month chart, 1-yr chart, all times chart. But the very least day, week, month, 1-yr. If you do that People will be hanging infront of their Portfolio lists all day long, I am 100% sure, at least I will.

Also why is it that I can't add attachments to this post - not super critical.

Lastly, make something so your site does not constantly crash due to data overload. Yahoo finance becomes 100x slower at market opening and market closing when most users are actively watching price changes. In many cases ticker symbols do not load so you cant even load the ticker and instead Yahoo spits out a table with suggested stickers. Happens non-stop ... C'mon learn from Google - they have zero delays and frozen website.
