Dividend Paying Stock Portfolio

Do the screens just pick the 10 stock portfolio & has the selection been the same for awhile? Seems like a no-brainer way to go based on performance, ease, expense. Just trying to get some clarity on this lazy portfolio.

Colors of plots

A lot of the colors used in plotting multiple investments (like the stock comparison graphs) are very close to each other. It's often very difficult to distinguish between them.

Is it possible to change these colors myself? If not, is that a feature in the pipeline?

Thanks

Transactional Portfolio Use

I am trying to understand how to make the best use of transactional portfolios. At first I thought it is useful when tracking the performance of a self-managed fund. You add cash to it, transact in equities, adding each transaction to the portfolio. It then shows you its performance wrt. to a benchmark. The broker does this for you anyway, but the whole reason I started evaluating Portfolioslab is so that I can separate my single broker account into thematic baskets ("thematic funds") and track their performance individually.

The transactional portfolio in Portfolioslab does not seem to work that way. It does not consider the changes in cash position, ie. any profit/loss made on equity transactions. It does not seem to be suited for track the assets of a fund, so to speak. What good is transactional portfolio then?
