Good app, Contacts list is WAY too wide though

I really enjoy using messenger on my phone and wanted to have that experience on my laptop. The app is just like facebook messenger BUT the contact list is WAY WAY too wide and you can’t resize it. I honestly can’t use this cause I find it so annoying. Please fix, and I’ll be glad to start using this and switch my score to 5 stars.
