Today a new dev (means "in development" :) version 0.9.20 was released. It has a new crash reporting solution, each time you catch a crash in Telegram Desktop, it will first check for the updates (perhaps a fixed version is already out?) and if not, it will suggest you to send us a crash report.

Speaking of small improvements: you can choose a sticker to be sent by an emoji you've written in the message field, just like in mobile apps now :)

If you would like to be the first in helping us testing all the new features we make you can install dev version from the bottom of this page: https://desktop.telegram.org/#dev-version
