Speedups confirmation message

I'm not sure if this has been posted before.. but wanted to suggest this: Add a confirmation message when clicking to use gems to speedup something (like upgrading a building, training units, making items, etc.).

Theres currently a confirmation message to destroy a building.. One to buy items..

I've accidentally clicked and spent gems a few times now on trivial upgrades/items.. gems that have taken a long time to save up. It is very frustrating to say the least. A confirmation box would be greatly appreciated!

That's probably by design and a wonderful source of gems for BB.
Why else would the issue be unresolved after 5 years of complaints?

Could be true, but doesn't hurt to ask. Those that pay to play would likely continue doing so. Those that don't likely won't. If this has been an issue from the start, I can't imagine how many players have been frustrated due to this. Fixing a pain point could help keep customers/players happy and more likely to keep playing (whether they pay or not).
