Constantly up to date and always ahead of every other IM  sometimes also ahead with features not present even in some other applications like (video players  image editing  cloud storage and media management). I really like it. I admire their product life cycle and their releases which are very often and fast  Telegram must have good scrum masters  developers and management for sure :D I would like to see more attention involved in the Cloud Storage management  because it is very easy in the current version to delete accidentally a chat and therefore lose all your cloud storage with that chat. Maybe we can have a lock with pin/password/email confermation to delete a chat which we mark as 'important' and on the other hand to delete 'unimportant' chat could be without asking for password/pin/email confermation. I would also like to see a better organization of chats  groups  channels  so for example  when you have 4-5 private group where you are collecting info and stuff about 4-5 cities (1 city for each group)  then you want to have those groups grouped together in a 'master group' called for examples 'Cities for holiday'... and some other improvements are needed :) Good job!!!!!!!!
