Support for Importing zip or multiple files and only allow importable file formats.

Insomnia usually exports all the workspaces into a zip and I’ve tried to import that but it just doesn’t work and keeps loading. A few suggestions

1. When importing only show the formats that can be imported and grey out the others. I’m able to select any file in the select file dialog, it would be great to know which file formats are supported.

2. Show errors when import fails. When I try to import a zip file, it just keeps loading endlessly and I’m unable to tell if it will ever finish or if it failed.

3. Allow importing of multiple files/workspaces or a zip. For those who have been using other clients for a while, there are usually many workspaces and it becomes a pain to import all of them one by one especially if you work from more than one laptop.
