I am running Coolendar, an interesting hybrid calendar / todo mananger. it's great on the PC.
However, there's no smartphone version. You're supposed to use the "mobile" website.
So I logged into it via my Google account. That works.
However, the "filter by hash tag" doesn't work.
What's more, the field doesn't display all the content in that field. Scrolling is impossible.
WHO THE **** designed it? It's "optimized for tablets", apparently!
