Really poor flexibility. You cannot schedule classes for example Monday through Thursday... You get daily... every.single.day including weekends, there's not even WEEKDAYS... or weekly or monthly, etc... GOTTA have flexibilty when click week to get, for example, Mon Wed & Fri.... OPTIONS, man, OPTIONS...

Get rid of the stupid character limit, how am I correct chapters with if there's a limit rendering the tool useless? No cookie for you!

This is the only converter that I could find that does both currency and units, so in that regard this could be a four or five star extension. However this extension could use some work because it is not very convenient. For example, if I always want to convert DKK to USD or USD to DKK, it would be nice to have an option to always have those two currencies selected. But it also resets to the defaults which are EUR and USD. Same for unit conversion. I'd like to have the extension give me the option to select my preferred units, the ones I use the most, so I won't have to waste 20-30 seconds each and every time reselecting everything. I just want to click the extension button and start typing in numbers without having to search through the drop down menu every time. Not only that, if I wanted to select DKK from the drop down menu, I'd have to scroll for two minutes to find it. There is no "search" option where I could just type "D" and see all the entries that begin with "D". Since this extension is too inconvenient, I am going to uninstall it. I would rather use two different extensions, one for units and one for currencies, if they remember my preferred units and all I have to do is type numbers.
