Here's my list of issues, that if they would be solved, SI would be my best PPC tool:

Can't see the change amount/% of each KPIs for current period vs previous.

After filtering the portfolio, and try to filter campaigns after this, I see not only the campaigns from the filtered portfolio "Performance" section

If I select to go to a campaign I can't go to the set of placements for it.

If I changed the period of data in "keywords" I need to reaply filters. Filters need to be prioritized above selected the data range.

When I try to create a preset of filters, I can't create it by portofolio/name etc., only strictly based on KPIs.

When I filtered down some set of targets, I can't download them.

Can't exclude from the display of search terms, the ones that are already negated.

In Search Terms tab there's no total for the KPIs.

Can't enter a list of KWs as a filter.

Can't analyze and optimize the placements for SB campaigns.

Can't really set up the automation for placements based on my legend (if any of the placement is hitting sertain KPIs, to increse or decrease by a certain % without setting target KPI and mandatory selecting a specific placement
