It would be nice to be able to search for specific keywords in the description of parts in the results table. For example, it is difficult to find an ADC or DAC using I2C, but most datasheets have that in their description. So, instead, I could then just search for parts with the right bits/sample rate/etc. using the regular filters and finally search in the results table for a description containing "I2C". It may as well buffer the slow update speed of bad data topics.
I'm pretty wild about this site. The way to make a comparison between multiple suppliers is probably the easiest I have ever seen. Finding parts really is more fun here, but sometimes when you really need that one feature that the standard filters don't cover, your options are (for now) fairly limited.
