Resizable / responsive window

[amjd]

Hi. First of all, thanks for making this useful piece of software. I started using Taskr with version 0.4.0, which allowed one to resize windows, but it seems that this behaviour has been removed with version 1.0.0. Could you consider adding it back? It's a bit hard to go through the list in the small window when you have a lot of todo items. This is especially the case with larger windows, where you can't make use of all the available screen real estate.
